Question

6 sin(x)+3cos(x)-4sin(x)cos(y)+x=7pi
Find the slope of the tangent line to the curve


at the point (7pi,3pi/2)

Answer 1

Can you find the derivative of this equation?

Answer 2

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

Answer 3

I keep getting the wrong answer.

Answer 4

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

Answer 5

Your derivative is correct, maybe your substitutions are wrong

Answer 6

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

Answer 7

I'm not sure why

Answer 8

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

Answer 9

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