Hi there, I am getting a little bit stuck on a calculus question,
I am required to find the stationary points of g(x) = e^x/7 / sqrt (10 + x^2).
from this I need to use the first derivative test to classify each stationary point as a maximum or minimum.
A maximum corresponds to a stationary point where the second derivative g''(x) is negative, and a mininmum to a stationary point where the second derivative is positive.
(It's the second derivative test)
