ok, completely understood now, its been a while since I've taken calculus, u just completely jolted my memory, problem solved :) THANKS

attempt: α(t)=α0 cos(√(g/l) t) (3) 0=-g/l *α0 *cos(√(g/l) t) *dt^2 is this right? how do is solve for the right part??

ok ill try that thanks :)

i have no idea where to start :S

I need help on this question for my postlab, thanks ! By direct substitution, show that equation (3) is a solution of the differential equation (2) α(t)=α0 cos(√(g/l) t) (3) (d^2 α)/(dt^2 )=-g/l α (2) α = angle alpha in degrees α0 = amplitude of motion g =...
