The cotangent is the reciprocal of the tangent, so simply calculate, on your scientific calculator, 1 / tan(68).

It means inverse, and performs the opposite of the given operation. For example, if you want inverse of tangent, you will use that inv button.

"Rise per run" or something like that is the tangent function. Use your scientific calculator to calculate tan 30. Be sure to set your calculator to degrees first. Then - since you want the result in inches per foot - multiply this tangent by 12.

You would have to use its opposite tangent, tan-1on your scientific calculator. It would be tan-1(opposite side/adjacent side), and you must have the opposite and adjacent sides of the angle you are trying to solve.

Given only the measure of an angle, use a scientific calculator or a book of mathematical tables (if you can find one!). There are infinite series but they are not particularly easy to work with.

Use a calculator. There is no simple way to calculate it.

If you know the angle's sine, cosine, or tangent, enter it into the calculator and press &lt;inverse&gt; sine, cosine, or tangent. On MS Calc, in Scientific Mode, using Degrees, enter 0.5, then check Inv and the press sin. You should get 30 degrees. The other functions work similarly.
