Unfortunately this is a distance course, and there aren't many places I can go to for help... so bre with me. Question #1 (integral) (2 + 3cosx + (sinx)^3) / ((sinx)^2) dx $\int\frac{2 + 3cosx + (sinx)^3}{(sinx)^2} dx$ Developing... ((integral) (2/(sinx)^2) + (3cosx)/((sinx)^2) + sinx) dx Might want to write that out before attempting since it's a little difficult to read it properly when typed out. Note that (sinx)^3 should usually be written out (sin^3)x. Question #2 (1/4)^x * 16^(x/2) The answer, I believe, is 1. However I can't seem to reach this by applying exponential laws.
