## Homework Statement

Find the point, restricting [tex]x\in[/tex](-pi/2, 0), along the curve

f(x) = [tex]\frac{e^x}{cos(x)}[/tex]

where the slope of the tangent line to f has zero slope.

## The Attempt at a Solution

I found the derivative of f(x) and got:

[tex]\frac{e^x(cosx - sinx)}{cos^2(x)}[/tex]

Where would I go from here to find the point though?
