  2. Angular and Linear Velocity! • Elena can now reach 48 mph on her new exercise bike in high gear. These bike wheels are 25 in. in diameter, the pedal sprocket is 12 in. in diameter, and the wheel sprocket is 4 in. in diameter (in high gear). Find the angular speed of the wheel and of both sprockets in rad./hr.

  3. Belt Length! • If r1 = 18in. And r2 = 11 in. and the centers of the wheels are 36 in. apart, find the length of the belt.

  4. Applications of Trig Functions • A right circular cylinder is inscribed in a sphere of radius 20. Find a complete graph of the situation for the volume V of the cylinder in terms of the angle Ɵ. Find the dimensions of the cylindrical of maximum volume that can be inscribed in the sphere.

  5. Inverse Trig Functions Evaluating a Trig Expression Verifying an Identity Show that:sin-1x + cos-1x = π/2 for all x in [-1, 1]. • Write an algebraic expression in terms of v for sin(sin-1v) and cos(tan-1v).
