Find the coordinates of the stationary points for the curve y = x^4 - 2*x^2 + 5.
First solve to find dy/dx.dy/dx = 4x^3 - 4xThe stationary points occur when dy/dx = 0. Solve the equation to find the values of x for when dy/dx = 0.4x(x^2 - 1) = 0 x = 0, x = 1, x = -1Finally sub in the values of x into the equation for y to find the corresponding y values.y = 5, y = 8, y = 8
