I need help on this question for my postlab, thanks !(adsbygoogle = window.adsbygoogle || []).push({});

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 = gravity

l = length

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
