Basic Math

1) Find the following indefinite integrals.

    a) (4-3xsec^2 x)/x dx

    b) (5 sin^ 3 x ) / (1+cosx)(1-cosx) dx

2) A particle starts from rest and moves along the x-axis fromthe origin at t = 0 with acceleration

       a(t) =   6 - 2t(ms^-2) at time t. When and where will it come to rest.

       Remember dvdt =acceleration and dsdt = velocity

3) Use substitution to find the following integrals.

    a) (9x)/ sqrt of (3+x2) dx                        LetU = 3+x^2

    b) (dx) / (25- x^2 ) Let x = 5 sin U

4) Consider the integral 1? 1 / (2x+1)^3 dx.

    a) Explain why the integral is improper.
