A) Given that dr/dθ = 3/(1-r)^4 and r(0)=0, use the substitution u=1-r to find r in terms of θ.
B) The region bounded by the curves y=sin x, y=cos xand the x-axis between x=0 and x= π /2 is rotated about the x-axis.
i)Find the point of interesction of the two curves
ii) Calculate the exact value of the volume of the solid of revolution formed.
Cheers!
