[22:57] ask lol 15[22:57] omg hawt [22:57] what trig-,- [22:57] i might not knokw, but ask first 15[22:57] convert each angle to a decimal in degrees 15[22:58] 61 degrees 42' 21" [22:59] sorry dc'ed [22:59] could you ask again? 15[22:59] convert each angle to a decimal in degrees 15[22:59] 61 degrees 42' 21" 15[23:02] ne ideas> [23:03] so sorry but dc'ed again 15[23:04] haha [23:04] err 61'42'21"" 15[23:04] convert each angle to a decimal in degrees [23:04] right? 15[23:04] ya [23:04] well it is just 61 + 42/60 + 21/3600 15[23:04] 61 degrees 41 minutes 21 seconds 15[23:04] sumthin like that [23:04] (16:04:13) well it is just 61 + 42/60 + 21/3600 [23:04] ( 15[23:06] wait 15[23:07] does it have to be in degrees to turn to decimal or wut [23:08] x'y'z" ---> x + y/60 + z/3600 [23:08] so 61'42"21" is just 61.7058333 [23:09] 1 degree has 60minutes, 1 mintues has 60 seconds:P [23:13] here? 15[23:13] ya [23:13] got that? 15[23:13] so thats pretty easy then ? [23:14] well are you allowed to use calculator? 15[23:19] ya lol 15[23:19] its homework 15[23:19] but idk how to do the second angle thing 15[23:19] i got a couple more like that so im just doin it 15[23:21] do u know how to convert angles to DMS ? 15[23:25] cuz im pretty sure u gotta do it a different way than just *60 15[23:26] 61.24 = 61 14 24 question mark ? [23:26] oh [23:27] 0.24*3600 [23:27] =864 15[23:27] que ? [23:27] 864/60=14.4 15[23:27] dont u do .24*60 ? [23:27] actually wait 15[23:27] and get 14.4 [23:27] start again 15[23:27] and then do .4 * 60 15[23:27] and get 24 ? [23:27] 0.24*60=14.4 15[23:27] ya [23:28] 0.4*60=24 [23:28] 0.4 is from 14.4 take off 14 15[23:30] ya 15[23:30] so its 61 14 24 ? 15[23:30] correct ? 15[23:33] RONALDINHO [23:34] sorry dc'ed again [23:34] lol 15[23:34] so its 61 14 24 ? 15[23:34] YES? [23:35] yea 15[23:38] what if i have 39.6 for seconds 15[23:38] do i just round it 15[23:39] 29.411 = 7.411*60 = 0724.66 , 7.66*60 = 0739.6 [23:40] if it is exact value [23:40] then why round 15[23:40] well can u have a 39.6 as seconds 15[23:40] or not ? [23:41] i guess? [23:41] unelss there is a smaller unit than seconds Session Time: Wed Sep 30 00:00:10 2009 15[00:15] 135 degree angle 15[00:15] and 30 foot radius 15[00:15] = how much area ? [00:15] -,- [00:15] ok [00:16] what's the area of a full circle 30foots radius [00:16] hello? [00:16] i am helping 15[00:16] umm 15[00:17] 2826 [00:17] well 2827=.= [00:17] any way its 30 times 30 times pi right?> 15[00:17] ya [00:17] so how many degree in a circle-,- 15[00:18] 071,060.125 ? [00:18] well yea i got 1060.287521 but close enough [00:19] what you do is just to find area of full circle [00:19] devided by 360 then degrees [00:19] or devided by 2 pi if radian * whatever value 15[00:19] ya lol [00:19] why ask me then [00:19] so easy [00:19] lol 15[00:19] idk lol i forgot for a minute [00:20] xd 15[00:22] do u know angular speed and linear speed? [00:22] omega and shit? [00:22] physics 15[00:23] its like traveling around a circle with a radius of 5 cm and in 20 seconds 1/3 radians is swept out, whats angular speed + linear speed [00:24] is that the actually question? 15[00:24] ya [00:25] ok [00:25] angular speed is easy [00:25] 1/3 rad in 20seconds so, 1/3 over 20 is 1over60 rad per sec [00:26] linear.....err , circumference of a circle radius 5 is 2*5*pi [00:26] 10 pi over 2pi times 1/3 pi is [00:27] 5over 3 pi [00:27] that's in 20seconds [00:27] so 5 over 60 cm per sec or 1over 12 cm per sec [00:29] harro? 15[00:30] it says [00:30] says what 15[00:30] linear speed = distance traveled divided by time it took to travel that distance [00:31] (17:25:55) linear.....err , circumference of a circle radius 5 is 2*5*pi [00:31] whcih is 10pi [00:31] (17:26:24) 10 pi over 2pi times 1/3 pi is [00:31] (17:26:56) 5over 3 pi [00:31] you know whole cricle is 2pi, you only ewnt over 1.3 pi [00:31] 1/3pi [00:31] radian 15[00:31] o oook ook 15[00:33] howd u go from 5/3 pi , in 20 seconds to , 5/60 cm per second ? 15[00:34] o just 15[00:34] o ok i see [00:34] lol [00:34] 5over 3 times 1 over 20 [00:34] so 5 over (3*20) [00:34] sorry if i am too fast [00:34] or sorry if it isn't the way that your teacher uses [00:34] coz last time you said your teacher way is much easier lol [00:35] my way is to make you understand step by step kinda 15[00:35] lol 15[00:35] im dum for not realizin that [00:35] lol 15[00:35] like after i ask u a question im like 15[00:35] oh nvm im dumb [00:35] lol 15[00:35] sin < 0, cos > 0 15[00:35] name the quadrant in which the angle lies ? [00:36] full question pl0x 15[00:36] that is the full question lol [00:36] sin <0 OR sin x < 0 15[00:36] it says , [00:36] oh nvm same thign really [00:36] lol 15[00:36] so i fink both ? 15[00:36] ya lol [00:37] genereal solution or just 1? [00:37] general* 15[00:37] it says like which quadrant 15[00:37] does the angle lie 15[00:37] on a graph [00:37] oo quadrant [00:37] easy [00:37] you know what quadrants are? 15[00:38] ya [00:38] first quadrant is 0 to pi over 2 15[00:38] like top right, bottom right 15[00:38] o wut [00:38] 2nd is pi over 2 to pi [00:38] etc 15[00:38] WUT 15[00:38] i guess not 15[00:38] teacher went over it 15[00:38] sounded like jibberish to me [00:38] ok same thing [00:39] top right, is first quadrant, in radians , it is zero to pi over 2 [00:39] top left, 2nd quadrant in radians, it is pi over 2 to pi 15[00:39] last time i did radians was 4 yrs ago tbh >.> [00:39] bottom left, 3rd quadrant, pi to 3pi over 2 [00:39] bottom right, 4th quadrant, 3pi over 2 to 2 pi 12[00:40] ok so back to the questoin (17:35:43) sin < 0, cos > 0 15[00:40] its 1st quadrant? [00:40] no ok when is sin of an angle small than zero-,- [00:41] well i will tell you-,- 15[00:41] never ? [00:41] sin x is small than 0 when x is pi to 2pi [00:41] that's the 3rd and 4th quadrant 15[00:41] why is that [00:41] wtf.................. [00:42] you know how a sine graphs loosk like? 15[00:42] the bumps 15[00:42] /\/\/\/\ [00:42] nooooooo 15[00:43] im a fuckin downie [00:43] http://upload.wikimedia.org/wikipedia/commons/thumb/b/b6/Taylorsine.svg/300px-Taylorsine.svg.png [00:44] ignore the purple line 15[00:44] o fuck man 15[00:44] thats been like so long 15[00:44] since i seen that thing [00:44] anyway [00:44] sin 0 is 0 [00:44] then it goes up to 1 at sin (pi over 2) [00:45] then back down to 0 at sin (pi) [00:45] then further down to negative one at sin (3pi over 2) [00:45] then up back to 0 at sin (2pi) [00:45] then repeat 15[00:46] and which points on this graph is Pi/2 and 15[00:46] the first climax after 0 ? 15[00:46] kk lol i got it [00:47] yep 15[00:47] so like 15[00:47] the answer is 3rd + 4th quad ? [00:48] not for the whole question, only for sin <0 [00:48] for cos >0 15[00:48] ok [00:48] it is 1st and 4th [00:48] if you know how a cosine graphs looks like-,- 15[00:48] wait 15[00:48] isnt it 3rd and 1st ? 15[00:49] http://www.intmath.com/Trigonometric-graphs/cos.gif [00:49] look carefully [00:49] from 0 to pi over 2 it is >0 [00:49] then from "pi over 2" to "3pi over 2" it is <0 [00:50] and that's across 2 quadrants [00:50] 1 quadrants is every "pi over 2" 15[00:50] how the fuck do u know which quadrant it is wtf .. [00:51] sigh wait 15[00:51] the first quadrant is from 0 to pi/2 ? 15[00:51] o ok 15[00:51] it just looks weird 15[00:51] cuz itsl ike half as big as the others 15[00:52] on this graph 15[00:52] but wouldnt that make it 2nd and 4th 15[00:52] so confused 15[00:57] * Hiitsnick waits [00:57] k i made it clearer for oyu [00:57] wait [00:57] http://img97.imageshack.us/img97/8950/cos.jpg 15[00:57] oooooooooooooooh [00:57] lol-,- 15[00:57] i fot there was only 4 15[00:57] not 8 15[00:58] 2 of each * [00:58] 2pi is arleady 4quadrants [00:58] so obviously 4pi is 8 15[00:58] ok 15[00:58] so anyways answer = 4 [00:58] 4th quadrants, or bottom right [00:59] so my drawing make it clearer for you? lol 15[00:59] yes but i dun c how its " bottom right" if its not a circle lol [01:00] http://upload.wikimedia.org/wikipedia/commons/thumb/c/c9/Unit_circle_angles.svg/720px-Unit_circle_angles.svg.png 15[01:00] omg 15[01:00] ronaldo 15[01:00] so like 15[01:00] lets c 15[01:00] 14500 for tuition [01:00] ignore the corrdinate 15[01:00] 17 credit hours 15[01:00] this class is 3 15[01:01] can i drop my class and hire u as private teacher for 2588$ a semester ? [01:01] lol [01:01] my english suck though 15[01:02] da fk 15[01:02] dude 15[01:02] my teacher [01:02] you can see my stence doens't amke sense sometimes 15[01:02] cant understand her either ..
