First Quadrant Platform

In class today, the equation to find the horizontal position for the first quadrant was brought up.

  • x(t) = 50 cos (9t)


How does this equation work?
Does it work for every value of t? Or does it only work for first quadrant values?

x(t)=50cos(9t) is a formula used to solve for t in other words.. Time. However im not sure if it is just for the first quadrant values.. Help?

Is it and why?
