14) Usedifferentiation to show that each of the solutions for the integrals i., iii., v., vi. above is true.
15) Ifcot(u)du=ln|sinu|+Cwhat doescot(12x)dx16) =
.
19)Break the integral into three less complicated integrals, then integrate.Hint: rewrite using the idea that a+bc=ac+bc, reduce, rewrite using reciprocal identities, then integrate.
