does anyone want a test of how smart they are? if you say "no", don't do this. if you say "yes", do this below.

solve the equations below:

$$\sin(45)=?$$

$$\cos(45)=?$$

$$\tan(45)=?$$

this is in degrees.

no calculators can be used for this, and I figured out this ONLY on PAPER!.

Pretty easy to do using unit circle concepts and   sin/cos = tan

you can do these in your head ....
