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?
