comment How can I find the area of the shadow?
It is easy to see that the shadow is circle with center at C and radius EC or CD I'm sorry I do not see how this is the case. As @JosuéMolina mentioned, why can't it be an oval?

@BenMillwood I'm sure the shape changes but the area might be constant.

comment Solve $\theta''+g\sin(\theta)=0$
@yoyo I simplified a step further & got this equation : $\frac{d\theta}{\sqrt{2C+2gcos\theta}}=dt$ I'm not sure I can integrate this.

Thanks. Seems obvious now that you have shown it.

Can you explain how it is in separable form? I'm a beginner so please bear with me..

comment Solve $\theta''+g\sin(\theta)=0$
@yoyo Can't it be done without the small angle approximation? I wanted to derive a general equation for all cases. Anyways I don't know how to solve even with the approximation, so it'll be helpful even if you explain that method.
