    If sin(t)=-1, then t would equal the arcsine of -1

    for my homework, the example problem is cos(t)=1, and the answer is 2(pi)n

    were you taught to derive your trig values using the unit circle?

    then you are looking for the angle that gives you -1. Look in the sine column

    did they tell you to just use 0 degrees to 360 degrees? Just the unit circle
