Use a graphing utility to graph two periods of the function. $$y=0.2 \sin \left(\frac{\pi}{10} x+\pi\right)$$
A water wheel has a radius of 12 feet. The wheel is rotating at 20 revolutions per minute. Find the linear speed, in feet per minute, of the water.
This exercise is intended to provide some fun with biorhythms, regardless of whether you believe they have any validity. We will use each member’s chart to determine biorhythmic compatibility. Before meeting, each group member should go online and obtain his or her biorhythm chart. The date of the group meeting is the date on which your chart should begin. Include 12 months in the plot. At the meeting, compare differences and similarities among the intellectual sinusoidal curves. Using these comparisons, each person should find the one other person with whom he or she would be most intellectually compatible.
Use a right triangle to write each expression as an algebraic expression. Assume that \(x\) is positive and that the given inverse trigonometric function is defined for the expression in \(x\). $$ \cot \left(\tan ^{-1} \frac{x}{\sqrt{3}}\right) $$
Will help you prepare for the material covered in the next section. $$ \text { Simplify: } \frac{-\frac{3 \pi}{4}+\frac{\pi}{4}}{2} $$
