Hello,
I have never taken a differential equations class. I have this problem that I could really use some help on.
Thx
A pendulum' motion is the following equation [tex] \ddot\theta = (\frac{-g}{l})\sin(\theta))[/tex]
I need to find the period of oscillations for various starting angles between 1 and 60 degrees. I am not to approximate [tex]\sin(\theta) = (\theta)[/tex] (that is for a later part.)
?
I don't know how to solve the D.E. The Boas book says its not solvable. I thought that the period would be between times where the acceleration is 0... so I set [tex] \ddot\theta=0[/tex], but didnt get very far with that.
I need to use Maple or some sort of Euler engine? I am clueless about this. Please help me, thank you.
