ATAN
The ATAN function returns the arctangent, or inverse tangent, of a number. It is commonly used in trigonometry and geometry 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 🔗
When you're dealing with angles and need to invert the tangent to find an angle based on the tangent of sides of a right-angled triangle, ATAN in Excel is the go-to tool. It's widely used in trigonometry, geometry, and various mathematical applications to determine angles based on the tangent of the sides of a right-angled triangle. The function returns the arctangent of a number, providing the angle in radians, which can be converted to degrees, if necessary. ATAN facilitates precise angle calculations, allowing for accurate geometric and trigonometric analysis within Excel.
Examples 🔗
To find the arctangent of 0.5, you would use the formula: =ATAN(0.5)
If the tangent of an angle θ is 0.75, you can find the angle in radians using: =ATAN(0.75)
For the tangent value of -1, you can calculate the arctangent by entering: =ATAN(-1)
Notes 🔗
The ATAN function returns the angle in radians, which may need to be converted to degrees for specific applications. This can be achieved by multiplying the result by (180/Ï€) or using the RADIANS and DEGREES functions for seamless 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.
