when the wheel has turned through an angle θ, P is at (x,y)=(cosθ,sinθ).
So, since the x-coordinate is at cosθ, Q has moved 1-cosθ left from its starting point.
You don't say how fast the wheel is turning, so there's no way for me to know how far it has turned in 1 second.
Examine the diagram. A piston rod, PQ, is
connected to a wheel at P and to a piston
at Q. As P moves around the wheel in a
counterclockwise direction, Q slides back
and forth.
there's a unit circle. origin to intersection at (1,0) is point P. Extending beyond the edges of the circle is a point Q that is connected to point P.
b)
What distance will Q have moved 1 s
after start-up? Give your answer to the
nearest hundredth of a unit
