Derivative of sin4x by First Principle [Limit Definition]
The derivative of sin4x is equal to 4cos4x. In this post, we will find the derivative of sin4x by the first principle, that is, by the limit definition of derivatives. The limit definition (i.e., first principle) of derivatives tells us that the derivative of a function f(x) is given by the following limit: $\dfrac{d}{dx}(f(x))$$=\lim\limits_{h\to 0} … Read more
