The question is: Prove that: $2tan^{-1}2=\pi-cos^{-1}\frac{3}{5}$ Hint: use the fact that $tan(\pi-x)=-tanx$ I did the question without using the Hint, bu...

This is a very simple first order ordinary linear differential equation: $$\frac{dy}{dx} + y = f(x) \tag{A}\label{A}$$, where $f(x)=\begin{cases} 2 \quad ...
