Determine the amplitude, the period, and the phase shift of the function and, without a graphing calculator, sketch the graph of the function by hand. Then check the graph using a graphing calculator. $$y=\frac{1}{2} \sin \left(2 x-\frac{\pi}{4}\right)$$

Find the function value using coordinates of points on the unit circle. Give exact answers. $$\tan \frac{3 \pi}{2}$$

Determine the amplitude, the period, and the phase shift of the function. Then check by graphing the function using a graphing calculator. Try to visualize the graph before creating it. $$y=-3 \cos (4 x-\pi)+2$$

Determine the amplitude, the period, and the phase shift of the function. Then check by graphing the function using a graphing calculator. Try to visualize the graph before creating it. $$y=5-2 \cos \left(\frac{\pi}{2} x+\frac{\pi}{2}\right)$$

Find the function value using a calculator set in RADIAN mode. Round the answer to four decimal places, where appropriate. $$\sin 11.7$$

Convert to radian measure. Round the answer to two decimal places. $$584^{\circ}$$

Height of a Kite. For a science fair project, a group of students tested different materials used to construct kites. Their instructor provided an instrument that accurately measures the angle of elevation. In one of the tests, the angle of elevation was \(63.4^{\circ}\) with \(670 \mathrm{ft}\) of string out. Assuming the string was taut, how high was the kite?
