**Trig Functions**

[tex]2y - 5 = \sin(144t - 45)[/tex]

How can I find when the object is at equilibrum? I know it's when y = 0, but how do I solve from there? I tried arcsine but it gives me a domain error.

How can I find the minimum in between [itex]0 \le t \le 10[/tex]?

Is the period of oscillation 0.625 degrees?
