dear friends,

sorry to bug you all with things that are lengthy and rather tedious. please help me solve these questions if possible.

i have tried them but i just cant do the integrals. please help

FIND THE FOURIER TRANSFORMS OF THE FOLLOWING.

f(t) = ( 1 - 1/t ) 0 <= t <= 2

( 1 + 1/t ) -2 <= t <= 0

( 0 ) otherwise

f(t) = ( e^-t cost ) t >= 0

( 0 ) t < 0

f(t) = e^at -2 <= t <= 2

0 elsewhere
