Determine the points in the interval (0, 2π) at which the graph of the function below has a horizontal tangent line.

-there should be 3 (x , y) values from smallest to largest x value

Step 1

For finding the points on a function f(x), at which, f(x) has horizontal tangent line, we need to find all x, for which f’(x)=0.

Step 2

Lets find all the points of the given function on interval (0, 2π), for which f’(x)=0. So first calcutale f’(x).

Step 3

Now solve for f&rs...
