For real number x, the notations sin x, cos x, etc refer to the value of the trigonometric functions evaluated at an angle of x rad If units of degrees are intended, the degree sign must be explicitly shown (eg, sin x°, cos x°, etc)So if we restrict the domain of f(x) = cosx in this way, we can define cos−1 x 1 −1 0 180° f(x) x f(x) = cos x 1 2 So now we say that our function f(x) = cosx has domain 0 ≤ x ≤ 180 and that it has an inverse, f−1(x) = cos−1 x This inverse function is also written as arccosx So, if the angle xFor a function f (x), the derivative is the limit of h f (x h) − f (x) as h goes to 0, if that limit exists \frac{\mathrm{d}}{\mathrm{d}x}(\cos(x))=\left(\lim_{h\to 0}\frac{\cos(xh)\cos(x)}{h}\right)
