In Exercises 83-88, use a graphing utility to graph the function. $$ f(x)=\arctan (2 x-3) $$
$$ \text { In Exercises 77-82, sketch a graph of the function. } $$ $$ y=2 \arccos x $$
In Exercises 19-34, use a calculator to evaluate the expression. Round your result to two decimal places. $$ \arcsin (-0.125) $$
Prove each identity. (a) \(\arcsin (-x)=-\arcsin x\) (b) \(\arctan (-x)=-\arctan x\) (c) \(\arctan x+\arctan \frac{1}{x}=\frac{\pi}{2}, \quad x>0\) (d) \(\arcsin x+\arccos x=\frac{\pi}{2}\) (e) \(\arcsin x=\arctan \frac{x}{\sqrt{1-x^{2}}}\)
In Exercises 109-112, sketch a right triangle corresponding to the trigonometric function of the acute angle \(\theta\). Use the Pythagorean Theorem to determine the third side. Then find the other five trigonometric functions of \(\boldsymbol{\theta}\). $$ \tan \theta=2 $$
