(fundamental theorem of calculus)
f'(x)=cos(2x) and f(0)=3 find f( pi/4)
it says the answer is 7/2
and I haven't quite gotten that.
maybe im missing a step or something at the end
because i just get radical 2 over +3

|dw:1325094062965:dw| it says to solve by both methods.  ive used the the first fundamental theorem of calculus. and antidifferentiation.  the answer is supposed to be 7/2  but i keep getting stuck with radical 2 over 2 + 3 at the end. can someone help me out lol
