Given y=2x(x^2-1)^5, show that dy/dx = g(x)(x^2-1)^4 where g(x) is a function to be determined.

y=2x(x2-1)5 --> y=uv, where u=2x; v=(x2-1)5 --> thus product rule required.u'=2v'=10x(x2-1)4Product rule: dy/dx = uv' + v'uTherefore...

Find the finite area enclosed between the curves y=x^2-5x+6 and y=4-x^2

Starting by factorising the curve equations: the first one factorises to y = (x-3)(x-2) and the second one becomes y=(2-x)(2+x). From this, a rough sketch of the curves can be drawn and it can be seen tha...
