Homework Equations
Letting d = Lcm
now we already know [tex]\partial^2\vartheta[/tex]/[tex]\partial t^2[/tex] = [tex]\alpha[/tex] = mgdT[tex]\vartheta[/tex] / I
I tried integrating the whole equation wrt dt
so [tex]\partial\vartheta[/tex]/[tex]\partial t[/tex] = [tex]\int mgd\vartheta/ I dt[/tex] (with limits 0->T) = mgd[tex] \vartheta[/tex]/ I
I only need help with this step. How do I deal with the [tex]\vartheta[/tex]?
