Aw man when did lmgtfy.app/?q=alteratives+to+sohcahtoa stop using Google? I didn't see anything great there. But here's a pitch: students also need to know x=cos y=sin on the unit circle (which match alphabetically). So take your triangle and divide by hypotenuse to get a triangle there...Permalink On twitter.com
