Use a scientific calculator to evaluate the trigonometric functions. Make sure the calculator is in DEGREE mode. Round to four decimal places. $$\tan 65^{\circ}$$

Graph the given pair of functions on the same set of axes. Are the graphs of \(f\) and \(g\) identical or not? $$f(x)=\sin (x+\pi) ; g(x)=-\sin x$$

Evaluate each trigonometric function without the use of a calculator. $$\cos \left(\arcsin \left(-\frac{12}{13}\right)\right)$$

Find a positive angle and a negative angle that are coterminal with it. $$\frac{\pi}{6}$$
