SIN
Definition: The SIN function in Excel is utilized to calculate the sine of an angle.
Syntax: ==SIN(number).
Situation: This function is beneficial when you need to compute the sine of an angle in radians.
Example: For an angle of 30 degrees, conversion to radians is necessary by multiplying it by pi/180. Hence, the formula becomes =SIN(30*pi()/180). This yields a result of 0.5, equivalent to the sine of 30 degrees in radians.
