MS 101 Alg & Trig test four • 28 June 2012 Name:

1. A RipStik was swizzled across a large sheet of paper. The swizzle wave can be seen in the diagram below.
   
   
   λ = _______________ Write the wavelength λ of the RipStik swizzle wave in centimeters.
2. a = _______________ Calculate the amplitude a of the RipStik swizzle wave.
3. τ = _______________ Calculate the period τ of the RipStik swizzle wave.
4. b = _______________ Given that $b=\frac{2\pi }{\tau }$, calculate b
5. y = ______ sin( _________ x). Given the general form y = a sin(bx) and the results above, write the equation for the RipStik swizzle wave.
6. _________ A tuning fork has a frequency of 384 Hertz. Calculate the period for the tuning fork.
7. ________ Calculate arcsin(0.707106782), report the result in degrees.
8. ________ Calculate $\arccos \left(\frac{\sqrt{3}}{2}\right)$, report the result in degrees.
9. __________ For a right triangle with an adjacent side of length 65 and an opposite side of 72, find the length of the hypotenuse r.
   
10. __________ For a right triangle with an adjacent side of length 65 and an opposite side of 72, find the angle θ in degrees.
    
11. Produce a "north pointing" hexagon inscibed in a circle with a radius of 100 pixels using SVG on your computer. Call me over when you are done and show me your correctly done hexagon in a circle SVG. You must finish this sufficiently prior to the end of the period for me to properly check your result.
