Math Help - Help needed in Intergration Questions

First post so bear with me if they dont come out right :-)
Im not too sure about the working, i have done this just now and came up with 30.375, the steps i have taken are a bit confusing though.
Thanks very much to anyone who gives me a hand.
1. Calculate at t=4



2. Calculate when t= 0.01sec
for this i ended up with 3.1354



I have a few others but any help with these would be greatly appreciated

hey mate,

I'm not exactly sure where you trouble lies, are you having difficulties evaluating f(t) at t = some value say t* ??

if you could elaborate on your problem a little further I would be more than happy to assist.
