Hello Asad You don't say what to differentiate with respect to, but I shall assume it is x. 9. (1/a)(2x/b - 2/a + d/x^2). It is arguable what the simplest expression is here. It may be 2x/(ab)

Hello Sneha This is not my expertise, but I will help you with some of them. cos(2B) = 2 cos^2(B) - 1 = 2/sec^2(B) -1 = (1-tan^2(B))/(1+tan^2(B)) Then, clearing the fraction: cos(A-C) -cos(A-C)tan^2(B)
