Find the derivative and following function and hence find the value of coordinates for when the function is at a stationary point:

y = e x x 2 + e x : 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: y I = F I (x)G...

A circular ice rink has a diameter of 60 meters. Calculate the area of the ice rink in terms of π in meters

Area of a cirlce = π x r^2 The radius (r) = the diameter / 2 So, r = 60/2 = 30 Therefore, the area of the ice rink = π x 30^2 = 900π
