Second
Differentiation
a) Find the maximum and minimum value of y = 2x3 −6x in the
range −0.5 ≤x ≤1.5
b) i)Find the derivative to y = cos(−3t2 + t + 4)
ii) give one t value when the derivative is equal to zero.
c) Pick an example function (take an easy one), y(x), and
demonstrate that the second derivative test gives a negative value
for a local maxima
