In the last lesson, you saw the computer display values for

`sin`

and `cos`

. The results are always some long decimal number
between -1 and 1. Strange huh? Here's a neat trigonometric identity you may have seen before. If you square the result of a `sin`

and add it to the square of a
`cos`

, you'll always get the same number. Do you know what this number is? Try out this code and see. (Hint: This is an example of the famous identity $\sin(x)^2+\cos(x)^2=1$.
