differentiation of sinx from first principal

In this video "Differentiation or derivative or differentiating of Sinx = Cosx from first principal" Derivative of Sine || Differentiate Sin X || Derivative of sin X is equal to cos X. To find the derivative of sin X its quite easy from first principle method. lather the result of this derivative lesson we helps us to find quickly the derivative of trigonometric functions. We will use this result as a standard result in later problems of derivative calculus in math.

I hope you understand how to prove derivative of sinx . In similar way we can find the derivative of cosine , derivative of tangent and other trigonometric function.

In the Previous videos we have proved derivative of Cos(x) = -Sin(x) and derivative of tan (x)= Sec^2(x)
