If you want to find the sine of 90 degrees, then you should first convert degrees into radians and then use the SIN formula available in Excel. Don’t worry, we are going to look at how to use trigonometric functions in Excel in minutes.
Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
Our example worksheet contains a spreadsheet to calculate the sine, cosine and tangent for 0 to 2π. Since the angles are already in radians, it’s straightforward to do these calculations. In the first row, type =SIN( and select the cell containing the angle (C5). Repeat for the cosine =COS(C5) and tangent =TAN(C5).
This article describes the formula syntax and usage of the SIN function in Microsoft Excel. Description. Returns the sine of the given angle. Syntax. SIN(number) The SIN function syntax has the following arguments: Number Required. The angle in radians for which you want the sine.
9 paź 2024 · To calculate the sine of 90 degrees in Excel, you can use the SIN function with the argument of π/2. =SIN(PI()/2) //returns 1. The PI () function returns the value of pi, and dividing it by 2 gives you the value of π/2. This will return the value of 1, which is the sine of 90 degrees.
If you want to find the sine of 90 degrees, then you should first convert degrees into radians and then use the SIN formula available in Excel. Don’t worry, we are going to look at how to use trigonometric functions in Excel in minutes. Excel provides functions for sine (sin), cosine (cos), tangent (tan), hyperbolic sine (sinh), hyperbolic ...
