@jim_thompson5910 the answer i got was Sin(A)+Cos(A) but apparently it is wrong :(

OpenStudy (anonymous):

@e.mccormick

OpenStudy (e.mccormick):

Well, let me look...

OpenStudy (e.mccormick):

First, did you do this? \[\frac{1+\cot A}{\csc A}\implies \frac{1+\frac{\sin A}{\cos A}}{\frac{1}{\sin A}}\]

OpenStudy (anonymous):

yes except for cotA i put \[\cos A/\]

OpenStudy (anonymous):

sorry CosA/Sin A

OpenStudy (anonymous):

tan is \[\sin A/\cos A\]

OpenStudy (e.mccormick):

Oh, yah... LOL It would be that.

OpenStudy (e.mccormick):

\[\frac{1+\frac{\cos A}{\sin A}}{\frac{1}{\sin A}}\implies \left[1+\frac{\cos A}{\sin A} \right]\cdot \frac{\sin A}{1}\]

OpenStudy (e.mccormick):

OK... Then.... ummmm.... how the heck is that wrong!

OpenStudy (anonymous):

Yeah! i have no idea. i actually put it in twice just to make sure but nope it wrong

OpenStudy (e.mccormick):

Did you try reversing them? Who knows. ANd putting in the () just like they have it?

OpenStudy (anonymous):

nope..it didnt work

jimthompson5910 (jim_thompson5910):

maybe it's case sensitive try cos(A) instead of Cos(A)

jimthompson5910 (jim_thompson5910):

but yeah I'm getting cos(A) + sin(A) or sin(A) + cos(A) too

OpenStudy (anonymous):

i didnt have to type it..the button for cos is there already so i just click that

jimthompson5910 (jim_thompson5910):

ok show us how you're inputting the answer, maybe that will help

OpenStudy (anonymous):

OpenStudy (anonymous):

those are all the answers

jimthompson5910 (jim_thompson5910):

well the only option not covered is cos(a) + sin(a) but that's basically the same as the other options

OpenStudy (anonymous):

yeah and I only have one more answer left so i dont want to risk it loll

jimthompson5910 (jim_thompson5910):

I would bring this up with a teacher and the teacher will be able to fix the error

OpenStudy (anonymous):

maybe i will just ask my professor thanks to everyone that helped me out!!

OpenStudy (anonymous):

does anyone know how to do this \[\cot (x)/\csc(-x)\]

OpenStudy (anonymous):

@e.mccormick

OpenStudy (e.mccormick):

Simplify, solve, what?

jimthompson5910 (jim_thompson5910):

cot(x) = cos(x)/sin(x) ------------------------- csc(-x) = 1/sin(-x) csc(-x) = 1/(-sin(x)) csc(-x) = -1/sin(x)

jimthompson5910 (jim_thompson5910):

use those facts to simplify

OpenStudy (anonymous):

simplify

OpenStudy (e.mccormick):

Yah, even odd properties.
