past exams questions...help~! hi i encountered a few difficult questions and i don't know how to solve them.. any help would be greatly appreciated: 1. Find the area of the cap cut from hemisphere X^2 + Y^2 +Z^2=2 (Z=>0) by the cylinder X^2 + Y^2=1 2. Use method of undetermine...

oh yea sorry i mean to write t instead of s..my bad~! but after looking at it again i got cos(t)/2 - e^t/2 + te^t/2 i think this one is correct..anyway thanks for all your help :)

for the first question t*e^t*sin(t) i got (2s-2)/((s-1)^2+1)^2 and for the L^-1{1/((s^2+1)(s-1)^2)} i got (e^s/8)-(s*e^s/4)-(e^-s/8)+(s^2*e^s/4) ...doesnt look right does it?

hi, i just started doing laplace transform n i have real trouble doing these two questions, anyhelp would be great... L{te^t(sint)} L^-1{1/((s^2+1)(s-1)^2)}
