anonymous · Answer

Can you find the derivative of this equation?

anonymous · Answer

1/4csc(x)csc(y)(4cos(x)cos(y)+3sin(x)-6cos(x)-1)

anonymous · Answer

I keep getting the wrong answer.

anonymous · Answer

All right. What the derivative of a function does is provide its slope at a point, so you should substitute x and y

anonymous · Answer

Your derivative is correct, maybe your substitutions are wrong

anonymous · Answer

Yeah, I'm getting error on my calculator. When I go to substitute it in..

anonymous · Answer

I'm not sure why

anonymous · Answer

I'll bet you're having parentheses trouble. Or maybe you tried to find csc (7pi)

anonymous · Answer

lol.. i did try to find csc(7pi), is that wrong?
