OK, I admit that I don't know much about calculators especially the TI-84 Silver edition.
here the question
during a hurricane, a 37 foot tree breaks at the base and falls against a nearby building. The top of the tree now stands 12ft above the ground. Find the angle between the ground and the base of the tree.
OK, so I use sin to find the angle, right?
it would be sin(12/37) but when I plug the number in it gives me a very ridiculus number.
when I press sin^-1(12/37) I got the result?
why and when will press sin^-1 instead of sin?????
