physics section on oat calculator

[ZooZoo]

Im confused im studying the kaplan big blue book and it includes sin and cosine and tangent how am I supposed to do it in my head for example inverse of tan 3 , you need to do that in order to find the direction. Any one that has taken the exam any thought about that if we need to know how calculate that? As well as decimal divisions that take some time?

Physics is very little calculations. All you need to do is know how to divide multiply add and subtract! As far as sin cos, you only should memorized the big ones like 30 and 60. I didn't have to calculate any of those in my exam
