limit using series expansion

Here, you will learn how to find limit of trigonometric functions and limits using series expansion with example. Let’s begin –  Limit of Trigonometric Functions $\displaystyle{\lim_{x \to 0}}$ $sinx\over x$ = 1 = $\displaystyle{\lim_{x \to 0}}$ $tanx\over x$ = $\displaystyle{\lim_{x \to 0}}$ $tan^{-1}x\over x$ = $\displaystyle{\lim_{x \to 0}}$ $sin^{-1}x\over x$ [where x is measured in […]
