<p>Can anyone point me to a site that'll help me learn the trig identies and such that appear on the ACT? I'm in College Algebra right now, but we don't start the trig portion until November, and I need to learn the trig radians and all of that for the ACT Saturday. = P I know basic Soh-Cah-Toa, but I don't know the more advanced trig, such as the maximum and miniums for each graph with radians and degrees. If anyone knows of a good site to learn and practice these concepts, please share! Thanks!</p>
<p>[Table</a> of Trigonometric Identities](<a href=“http://www.sosmath.com/trig/Trig5/trig5/trig5.html]Table”>Table of Trigonometric Identities)</p>
<p>Only tested on the first 3 I think.</p>
<p>All you need to know about ACT Trig is the SOH CAH TOA. They never ask you to convert from radians to degrees. Just so you know, the range of a sine or cosine graph is [-1,1]. But don’t worry about that. Just go on YouTube and watch some videos on BASIC Trig Functions.
Relax, it’s not too bad. Best of luck to you!</p>
<p>To convert from degrees to radians, just multiply by pi/180. It’s like doing a unit conversion from inches to centimeters. Not too hard.</p>
