Problem 25

Evaluating Trigonometric Functions Using Technology In Exercises $25-28$ , use a calculator to evaluate each trigonometric function. Round your answers to four decimal places.

$$\begin{array}{l}{\text { (a) } \sin 10^{\circ}} \\ {\text { (b) } \csc 10^{\circ}}\end{array}$$

Answer

(a) $\sin \left(10^{0}\right)=0.1736$

(b) $\csc \left(10^{\circ}\right)=5.7588$

Okay, so we use a cath later. We get that sign of 10 gritty physical to 0.1736 and then the coast, seeking 10 degrees is equal to what? That's one over sign from 10 degrees, because people do one over through a 0.1736 which gives that 5.7603
