1. Remember the Native American chief's name: SOHCAHTOA.
2. When an angle is missing, press the "second" button before pressing the function key.
3. If the variable is in the numerator of the fraction, multiply both sides of the proportion by the denominator.
4. If the variable is in the denominator, divide the numerator by the function and the angle in question.
5. Leave the trigonometric functions four places to the right of the decimal point.
6. Round the angle to the nearest whole number.
7. The only trigonometric function that can be greater than "1" is tangent.
8. The sine and cosine functions can not be greater than "1."
