Differentiate. y= (cos x)^x u= cos x du= sin x dx ln y = ln(cos x)^x ln y = x ln(cos x) (dy/dx)/(y)= ln(cos x) (dy/dx)= y ln(cos x) = (cos x)^x * (ln cos x) (dx/du)= x(cos x)^(x1) * (sin x) =  x sin(x)cos^(x1)(x)

Book works out integral of sqtr(a^2x^2)dx as a^2/2*arcsin(x/a)+x/2*sqrt(a^2x^2) by taking x=a sin theta, and advises to work it out using x=a cos theta. I did and got the first term as a^2/2*arccos(x/a)and the same second term.
