This proof helps clarify a fundamental The following (particularly the first of the three below) are called "Pythagorean" identities. Quando o seno de y é igual a x: sin y = x. When you say x tends to $0$, you're already taking an approximation.) The numbers in the expression given are rounded to four decimal places and we could add more terms of the form $\sin((2n+1)x)$, but their coefficients will get , Sal finished writing a very long expression: lim ∆x->0 [(cos x sin∆x + sin x cos ∆x - sin x)/x] I tried evaluating and got a wrong answer that the whole limit =(sinx-sinx)/x= 0/x, but why can't I just evaluate the whole thing here instead of using the limit properties and go through a lot of steps to get the final answer? Derivative of xsinx. Done! But most people like to use the fact that cos = 1sec to get: ddx tan(x) = sec 2 (x). Dive into the derivative of the function g (x) = 7sin (x) - 3cos (x) - (π/∛x)².
