How Excel sin functions use

The SIN function is to compute the sine function. It appears in the default common functions, math, and trigonometric functions of Excel functions.

Sin function grammar form: sin (number)

Sin function Application considerations:

1, number parameters are usually in radians, if the use of degrees will need to multiply PI ()/180 or use the RADIANS function to convert it to radians;

2, number can be a digit or a cell name;

3, number value can be numeric, logical value, date;

Sin Function Example:

Sample Table	A
1	1
2	False
3	0
4	1900-1-1

A is the column number in the table above, and the left 1-4 is the line number. Enter the result of the following formula in a cell:

Example 1, =sin (A1) result is approximately equal to 0.84147

Example 2, =sin (A2) result is the same example 1, because the value of true is considered 1;

Example 3, =sin (A4) has the result, the result and example 1, everybody tries, because the date in Excel is associated with the numeral, 1900-1-1 is regarded as 1, but the direct use formula =sin (1900-1-1) obtains another result;

Example 4, =sin (30*PI ()/180) result is 30 degree sine function result 0.5;

Example 5, =sin (RADIANS (30)) results as example 4;
