SIN COS TAN etc. |
|
Excel has most of the math and trig functions built into it. If you need to use the SIN, COS, TAN functions, they can be typed into any cell. If you wanted to find:
| angle | sin | cos | tan |
| REF | =sin(REF) | =cos(REF) | =tan(REF) |
| 0 | 0.00 | 1.00 | 0.00 |
| 30 | 0.50 | 0.87 | 0.58 |
| 45 | 0.71 | 0.71 | 1.00 |
| 90 | 1.00 | 0.00 | |
| 180 | 0.00 | -1.00 | 0.00 |
formula format = sin (degree * pi()/180) returns answer in degrees
formula format = sin (degree) returns answer in radians
To calculate trig functions in degrees you must enter them in convert them - otherwise
excel will calculate them in radians.
You can type in either an actual number for the REF or you can also type in a reference from the excel spreadsheet (like A2).
