Find the coordinates of the stationary point of the curve $\displaystyle y=e^xcosx$ for 0 is less than or equal to x and x is less than or equal to $\displaystyle /pi$ . Leave your answer in exact form.
Correct.
Now solve $\displaystyle \frac{dy}{dx} = 0 \Rightarrow \cos x - \sin x = 0 \Rightarrow 1 = \tan x$ over the given domain.
Then find the y-coordinate corresponding to the solutions for x found above.
