Proof derivative of sinx
WebTo derive the derivative of cos x, we will use the following formulas: cos x = 1/sec x. sec x = 1/cos x. d (sec x)/dx = sec x tan x. tan x = sin x/ cos x. Using the above given trigonometric formulas, we can write the derivative of cos x and the derivative of 1/sec x, that is, d (cos x)/dx = d (1/sec x)/dx, and apply the quotient rule of ...
