For the simple right-angled triangle below, the sine of the angle θ, is the ratio of the opposite side, o, to the hypotenuse, h.The trig. ratios are discussed further on the Wikipedia Trigonometric Ratios Page
The Excel SIN function calculates the sine of a given angle.
The syntax of the function is:
Converting from Degrees to Radians
If your angle is in degrees, you will need to convert it into radians before supplying it to the Sin function.An example of this is given below.
The following spreadsheet shows the Excel Sin Function, used to calculate the sine of four different angles.
Note that in the above examples:
