$$ \text { In Exercises 49-58, find the exact value of the expression. } $$ $$ \csc \left[\arctan \left(-\frac{5}{12}\right)\right] $$
Define the inverse cosecant function by restricting the domain of the cosecant function to the intervals \([-\pi / 2,0)\) and \((0, \pi / 2]\), and sketch its graph.
In Exercises 19-34, use a calculator to evaluate the expression. Round your result to two decimal places. $$ \arccos (-0.41) $$
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) \(\arcsin x=\arctan \frac{x}{\sqrt{1-x^{2}}}\)
Define the inverse secant function by restricting the domain of the secant function to the intervals \([0, \pi / 2)\) and \((\pi / 2, \pi]\), and sketch its graph.
