Summary: Use Excel to perform sine, cosine, tangent, and other trigonometric functions.
Microsoft Excel 2003 has many built-in trigonometric functions:
Returns the sine of ANGLE
Returns to cosine of ANGLE
Returns the tangent of ANGLE
By default, the angle is measured in radians; to convert an angle measurement from degrees to radians, use the =radians(ANGLE) function.
Excel also has the hyperbolic trigonometric functions:
Hyperbolic sine of ANGLE
Hyperbolic cosine of ANGLE
Hyperbolic tangent of ANGLE
Excel does not include the secant, cosecant, or cotangent functions. However, these can be figured by using the basic trigonometric functions.
If you have the result of a trigonometric function and want to find the angle (in radians) that you would need to get that result, use the inverse functions:
Inverse sine of SINE
Inverse cosine of COSINE
Inverse tangent of TANGENT
Inverse hyperbolic sine of HYPERBOLICSINE
Inverse hyperbolic cosine of HYPERBOLICCOSINE
Inverse hyperbolic tangent of HYPERBOLICTANGENT
To obtain the angle in degrees, enclose the above functions in the =degree() function,
Returns the angle, in degrees, of the inverse sine of SINE
