Derivative f’ of the function f(x)=sinx is: f’(x) = cos x for any value of x. Derivative of sin x Derivative $f’$ of the function $f(x)=\sin x$ is: \(\forall x \in ]-\infty, +\infty[ , f'(x) = \cos x\) Proof/Demonstration \[\begin{aligned} \frac{\sin (x+...
Derivative f’ of function f(x)=arctan x is: f’(x) = 1 / (1 + x²) for all x real. To show this result, we use derivative of the inverse function tan x. Derivative of arctan x Derivative $f’$ of function $f(x)=\arctan{x}$ is: \(\forall x \in \mathbb{R} ,\q...
cos x = sin ( π2 − x). A function of any angle is equal to the cofunction of its complement. (Topic 3 of Trigonometry).Therefore, on applying the chain rule:We have established the formula.The derivative of tan xd dx tan x = sec2x ...
( (sin)(t)d/(dt)[(tan)(t)]+(tan)(t)d/(dt)[(sin)(t)]) The derivative of ( (tan)(t)) with respect to ( t) is ( ((sec))^2(t)). ( (sin)(t)((sec))^2(t)+(tan)(t)d/(dt)[(sin)(t)]) The derivative of ( (sin)(t)) with respect to ( t) is (...
