solve part (d) Consider the ellipse +5 = 1. (a) Show that the circumference of the ellipse is given by C = 4 2 V4 cos? t + 9 sin? t dt. 7/2 (b) Show that this integral can be simplified to C = 8 S2 /1+ sin? t dt. (c) By taking u=sin(t), show that it further simplifies to C = 8 1 1+5u²/4 1-u? du. (Be careful, as this is an improper integral.) (d) Now make a substitution x = ? to find C = 8 9/4 a dz (Also improper.) Vz(z-1)(9-42)
