The use of sin in Excel with sine function

Introduction to the formula of sin function

Grammar: SIN (number)

Number is the angle, in radians, that requires a sine.

Note: If the unit of the parameter is degrees, you can multiply PI ()/180 or use the RADIANS function to convert it to radians.

The use method of sin function

Of course, sometimes it can be used directly, please see the following example:

=sin (Pi ()) PI radians sine (0, approximate)

=sin (PI ()/2) PI/2 radians sine (1)

=sin (30*PI ()/180) 30 degrees of sine (0.5)

=sin (RADIANS (30)) sine of 30 degrees (0.5)

Known radians or degrees (°), using the SIN function result

sine function: =sin (A2), at this time the value of cell A2 should be in radians, if A2 for the "degree" as the unit, the formula for its sine is written as "=sin ((A2*pi ()/180)";

sine function, cosine, tangent, cotangent respectively are "=cos (A2)", "=tan (A2)", ")", "=1/tan (A2)", other same sine function.
