0. All displayed math formulas should be indented.
1. Remove these lines.
2. It is bad style to keep the old version and then explain at the end the changes you would make to the old version. Just change the old version to your new version.
3. State the problem more clearly. Is it to prove the maths formula as an identity or is it to solve it as an equation?
4. In TeX \displaystyle \sin x is written as \sin x and not Sin x.
