ATAN
The ATAN function returns the arctangent, or inverse tangent, of a number. It is used in trigonometry to calculate angles based on the tangent of a right-angled triangle's sides.
Syntax 🔗
=ATAN(number
)
number | The tangent for which to find the arctangent. |
notes | The ATAN function returns the angle in radians, which can be converted to degrees by multiplying by (180/Ï€) or using the RADIANS and DEGREES functions. |
About ATAN 🔗
Use the ATAN function in Excel to find the angle whose tangent is a given number. This is useful when working with right-angled triangles and you need to determine an angle based on the tangent of its sides. The function returns the result in radians, which you can convert to degrees if needed. This makes it handy for trigonometric and geometric calculations.
Examples 🔗
To find the arctangent of 0.5, use the formula: =ATAN(0.5)
If the tangent of an angle θ is 0.75, find the angle in radians by using: =ATAN(0.75)
For the tangent value of -1, calculate the arctangent by entering: =ATAN(-1)
Notes 🔗
The ATAN function returns an angle in radians. You might need to convert this to degrees for some applications. You can do this by multiplying the result by (180/Ï€) or use the RADIANS and DEGREES functions for conversion within Excel.
Questions 🔗
The ATAN function returns the arctangent of a number in radians, representing the angle whose tangent is the specified number.
How can I convert the result of the ATAN function to degrees?To convert the angle from radians to degrees, you can multiply the result of the ATAN function by (180/Ï€) or use the RADIANS and DEGREES functions in Excel.
