trig function question

Postby eagle2020 » Tue Dec 06, 2016 8:00 am

Rachel is bowling with her friends. Her bowling ball has a radius of 4.3 inches. As she bowls she tracks the location of the finger hole above the ground. She starts tracking the location when the finger hole is at the 12 o'clock position and she notices that she got some backspin on the ball and it rotates counter-clockwise.
the finger hole changes by 45 degrees

Define a function,
f that gives the height of the finger hole above the ground (in inches) in terms of the angle of rotation (measured in radians) it has swept out from the 12 o'clock position,
