<p>Are there any questions where it could affect your answer? Isn't the only difference between the 2 modes that they give you different answers when you plug in sin/cos/tan functions?</p>
<p>You have it right. If you don’t use trig, then it does not matter at all. </p>
<p>You should never have to use either on the SAT 1
Edit: Though you are probably just wondering about how those unnecessary functions affect the rest of the calculator</p>
<p>For SAT I, you don’t need trig.</p>
<p>For SAT II, hopefully you know how to convert from degrees to radians or vice versa.</p>
<p>One thing to know about the SAT I is that there are lots of ways to attack the problems. You don’t have to use trig, but some people prefer to use SOHCAHTOA when they are dealing with special triangles. Some students even find it quicker to use the law of sines. (Try it yourself and you may be surprised.) For those applications, you should be in degree mode. But I think that OP’s concern was whether radian mode affected anything else. On that account, no worries.</p>
<p>sat math doesn’t test any trig…</p>
