A curve C has equation y = x^2 − 2x − 24sqrt x, x > 0. Prove that it has a stationary point at x=4.

A stationary point is where the curve has 0 gradient. So to prove that x=4 is a stationary point, we must find the equation of the first derivative. To do this, differentiate x 2 - 2x - 24sqrtx. It might hel...

Find the volume of revolution about the x-axis of the curve y=1/sqrt(x^2+2x+2) for 0<x<1

The volume of revolution is given by integrating Pi y 2 dx from 0 to 1.Squaring, y 2 =1/(x 2 +2x+2)Completing the square, we see that y=1/((x+1) 2 +1)Make the substitution u=x+1, so du=dx. When x is 0, respe...
