<p>Basically the Princeton Review book asks questions on the multiple choice where it includes sin and cos, but I don't believe you're allowed to use a calculator? Are you supposed to memorize them?</p>
<p>This may sound like a stupid question, but I just started self studying..</p>
<p>Are you referring to the section on oscillations?
I took AP Physics B last year and while you’re not allowed to use a calculator, you really don’t need one, since almost all of the problems are conceptual and require minimal computations. You shouldn’t have to worry about memorizing sin and cos functions.</p>
<p>On the section over inclined planes you need to know the sin/cos of the incline angle to answer some of the questions they give you, and I don’t see how I would do that without a calculator?</p>
<p>They will give you values of the sine and cosine functions at that particular angle. You just need to be able to pick the correct one to use.</p>
<p>On the multiple choice, you are provided with constants and conversion factors, unit symbols, prefixes, and common trig values (it’s page two in the pdf linked below). Although you don’t have to memorize the values, you must be able to use trigonometry in order to correctly determine component forces and such. </p>

<p>Hi, this might seem irrelevant to the thread but I have some Physics problems I just can’t solve and do not understand the explanations either.
Can you guys please try to answer them or at least check them out at this link</p>

<p>BTW, will the real exam be this hard?
(I can do the multiple choice but I have problems with these free responses)</p>
<p>Thanks</p>
