arcsin(0.8) with your calculator in rad

if it's not in rad, multiply the arcsin by 180/pi

Yes! Thank you very much. So, it says to find the radian measure of tangent -.25 now. Do I put in tan -.25 eeeerrr, am I doing this completely wrong? haha

type -.25, then click on the button that says "inv", then you'll see "tan-1" where "tan" used to be. Click that and you have an answer.
