Urgent.

Problems are:

1) initial value problem:

ds/dt=28t(7t^2-5)^3, s(1)=6

2) A moving ball on a line is v=ds/dt=3 sin 2t m/sec for all t. If s=0 when t=0, find s when t= pi/2 sec.

3) Find the derivative of d/dx (integral) (upper limit) sq rt x (lower limit) 3pi of cos t dt.

Its only 3 questions. Need it asap.
