Calculus help?

Question

Could you please explain how to do this problem?

Find the tangent to the curve y=4+cotx-2cscx
at the point (pi/2,2)
thankyou

whats the derivative, how do you find it??

Answer 1

The value of the derivative of a function is the slope of the original function at every point. To solve this problem, find the derivative and evaluate it at (pi/2,2)

Answer 2

Since you are looking for the tangent, take the derivative. And you are curious about the point where x = pi / 2, so plug in pi/2 for x in the derivative and that will give you the answer.
