WebJan 22, 2024 · Let’s prove that the derivative of sin (x) is cos (x). Thankfully we don’t have to use the limit definition every time we wish to find the derivative of a trigonometric function — we can use the following formulas! Notice that sine goes with cosine, secant goes with tangent, and all the “cos” (i.e., cosine, cosecant, and cotangent ...
WebWell, this one's going to be negative sine of x. So the derivative of sine is cosine, and the derivative cosine is negative sine. And then finally, the derivative of tangent of x is equal to 1 over cosine squared of x, which is equal to the secant squared of x. Once again, these are all very good things to know.
