Find all critical points of g(θ) = eθ cos(θ) in the interval 0 ≤ θ ≤ 2pi and classify them as local minima or maxima.
θ = (smaller value)
θ = (larger value)
need some help please thanks

Is this your equation?
$\displaystyle g(\theta) = e^{\theta}\cdot \cos {\theta}$
First find the derivative. Then find the values of x for which the derivative is equal to 0 or undefined.
Then use a sign chart to find where the function is increasing/decreasing.
When the function goes from increasing to decreasing, you have a local maximum and vise versa.
