Given y = 2x(x2 – 1)5, show that (a) dy/dx = g(x)(x2 – 1)4 where g(x) is a function to be determined. (b) Hence find the set of values of x for which dy/dx > 0

Given y = 2 x ( x 2 – 1) 5 , show that (a) d y/dx = g( x )( x 2 – 1) 4 where g( x ) is a function to be determined. dy/dx= (2)( x 2 – 1) 5 + (2x)*5(x 2 – 1) 4 (2x) dy/dx= ( x 2 – 1) 4 ( 2( x 2 – 1) + 20x 2 )...
