To supply an angle to COS in degrees, multiply the angle by PI()/180 or use the RADIANS function to convert to radians. For example, to get the COS of 60 degrees, you can use either formula below: =COS(60*PI()/180) =COS(RADIANS(60))
With Excel, this conversion can be written PI ( )/180. For example, to convert 45° to radians, the Excel expression would be 45*PI ( )/180 which equals 0.7854 radians. Excel has a built-in function known as RADIANS (angle) where angle is the angle in degrees you wish to convert to radians.
Returns the cosine of the given angle. If the angle is in degrees, either multiply the angle by PI()/180 or use the RADIANS function to convert the angle to radians.
Here’s how you can convert it: =RADIANS(180) converts 180 degrees into radians, essential for functions like SIN or COS. Similarly, if you have a result in radians and need to interpret it in degrees, =DEGREES(PI()) converts the value of π radians (about 180 degrees) back to degrees.
The function to convert B5 to radians is nested within the SIN function. You could also use =SIN(PI()/180*B5) if you prefer to use the formula on the previous page. Repeat for the cosine and tangent functions: =COS(RADIANS(B5)) and =TAN(RADIANS(B5)) , respectively.
11 maj 2024 · Method 2 – Cos Squared in Excel for Angles in Degrees. This method requires converting the angle values from degrees to radians, as the COS function accepts only angles in radians. Steps. Select cell C5 and enter the formula: =COS(B5*PI()/180) Press ENTER to execute the formula.
21 lut 2023 · Excel's trigonometric functions use radians, so this formula will perceive the X values as radians as well. If you want your X-axis to be on a pi-radian scale rather than a radian scale, you can multiply the cell reference by pi using the PI function in Excel. =(A3*PI()*COS(A3*PI())*SIN(A3*PI()))^2.
