Find the derivative and following function and hence find the value of coordinates for when the function is at a stationary point:
y = exx2 + ex : The derivative can be found using the chain rule. (A reminder of the chain rule: if y is a product of two functions of x i.e if y = F(x)G(x) , the derivative is as follows: yI = FI(x)G(x) + GI(x)F(x). ) So for the function in this question, you can start by finding the derivatives of each component then it's as easy as substituting them into the formula above. For ex the differential is also ex (This is
