Identities for the sine and inverse sine: The graphs of the functionsy= Cosxandy= Cos−1xare reflections of each other about the liney = x. The graphs of the functionsy= Sinxandy= Sin−1xare also reflections of each other about the liney = x(see Figure 6). Figure 6 Symmetry of...
\sin ^{-1}(x)+\cos ^{-1}(x)=\frac{\pi}{2} \\ Inverse tangent Just as before: Form the graph we can get that tan^{-1} is odd and it has domain R and range (-\frac{\pi}{2},\frac{\pi}{2}). Now let’s differentiate y = tan^{−1}(x) with respect to x. x ...
sin(θ) = Opposite / HypotenuseAnd Inverse Sine is :sin-1 (Opposite / Hypotenuse) = θWhat About "cos" and "tan" ... ?Exactly the same idea, but different side ratios.CosineThe Cosine of angle θ is:cos(θ) = Adjacent / HypotenuseAnd Inverse Cosine is :...
Inverse sine,cos, tan --What they are and how to use them to find the measure of an angle in a right triangle.
The inverse sine function is sometimes called the arcsine function, and notated arcsin x. y=sin−1xy=sin−1x has domain [−1, 1] and range [−π2, π2][−π2, π2] The inverse cosine function y=cos−1xy=cos−1x means x=cosyx=cosy. The inverse cosine...
The inverse trig integrals are the integrals of the 6 inverse trig functions sin-1x (arcsin), cos-1x (arccos), tan-1x (arctan), csc-1x (arccsc), sec-1x (arcsec), and cot-1x (arccot). The integration by parts technique (and the substitution method along the way) is used ...

In calculus, sin−1x, tan−1x, and cos−1x are the most important inverse trigonometric functions. Nevertheless, here are the ranges that make the rest single-valued. If x is positive, then the value of the inverse function is always a first quadrant angle, or 0. If x is ...
