More Foldable!
Flip your foldable over to the backside (the only part left blank) and add these titles to each box:
next, draw this example triangle and set up the sin ratio:
and then solve for theta using inverse sin or acrsin:
then draw this example triangle and set up the cos ratio:
and solve for theta using inverse cos or arccos:
Lastly, let's do the same for tangent, start with the example triangle and set up the tangent ratio: then solve for theta using inverse tan or arctan:
When you're all done it should look like this:
or like this:
