Question:
I'm a little confused about this. Why is arccos of 0 pi/2, 3pi/2, and 5pi/2? Isn't it just pi/2?
And since time can't be negative, the answer can't be t+v = pi/2
Also, when evaluating an inverse trig function set equal to 0, do I find the inverse trig of both sides (such as shown in this example?)
Thanks, let me know.
