<p>When do you have to alternate between the two during Math IIC? Like for what problems?</p>
<p>They'll specify which one they want. Also you can tell by the answers.</p>
<p>yeah.. if you se a pi in a question or an answer => change to radian... if you see degree in question/answer => change to degree..</p>
<p>sparky says they usually use degree, so keep calc on degree.. until u se a pi... don't forget to change back after u finish the question!</p>
