Week 16 – The Trig Review

this week in math we did a little review of last years trigonometry unit and I wanted to share it with you guys.

What we have here with SOH CAH TOA are the ratios dependent on how you can solve which part of the triangle

I have the sides labelled on the big triangle below as well as the ratios in between, naturally hypotenuse will be the longest side, adjacent will always be the side with the reference angle and the right angle, and finally opposite will only have the right angle on it’s side.

on the right side of the picture I have demonstrated how to find an angle and a side using the cosine ratio, as you can see it is fairly simple
