RADIANS function - Microsoft Support
The RADIANS function syntax has the following arguments: Angle Required. An angle in degrees that you want to convert. Example. Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, …
SIN function - Microsoft Support
Syntax. SIN (number) The SIN function syntax has the following arguments: Number Required. The angle in radians for which you want the sine. Remark. If your argument is in degrees, multiply it by PI ()/180 or use the RADIANS function to convert it to radians. Example.
DEGREES function - Microsoft Support
Converts radians into degrees. This math function requires a value for an angle. For the general formula, you can use *PI ()/180 to get the radian value.
ATAN function - Microsoft Support
This article describes the formula syntax and usage of the ATAN function in Microsoft Excel. Description. Returns the arctangent, or inverse tangent, of a number. The arctangent is the angle whose tangent is number. The returned angle is given in radians in the range -pi/2 to pi/2. Syntax. ATAN (number)
Math and trigonometry functions (reference) - Microsoft Support
Lists all math and trig functions, such as the SUM, SUMIF, SUMIFS, and SUMPRODUCT functions.
COS function - Microsoft Support
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.
TAN function - Microsoft Support
Returns the tangent of the given angle. This requires the values to be a number. If your argument is in degrees, multiply it by PI ()/180 or use the RADIANS function to convert it to radians.
ACOS function - Microsoft Support
This article describes the formula syntax and usage of the ACOS function in Microsoft Excel. Description. Returns the arccosine, or inverse cosine, of a number. The arccosine is the angle whose cosine is number. The returned angle is given in radians in the range 0 (zero) to pi. Syntax. ACOS (number)
COS function - Microsoft Support
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.
IMARGUMENT function - Microsoft Support
Description. Returns the argument (theta), an angle expressed in radians, such that: Syntax. IMARGUMENT (inumber) The IMARGUMENT function syntax has the following arguments: Inumber Required. A complex number for which you want the argument . Remarks. Use COMPLEX to convert real and imaginary coefficients into a complex number.
LINEST function - Microsoft Support
The LINEST function calculates the statistics for a line by using the "least squares" method to calculate a straight line that best fits your data, and then returns an array that describes the line.
