How do you calculate atan?
To convert degrees of slope into percentage of slope, use Slope-in-percent = Tan(Slope-in-degrees * Pi/180). To convert slope in percentage to slope in degrees, use Slope-in-degrees = Atan(slope-in-percent)*180/Pi.
What does atan mean in trig?
Arc tangent function. ATAN(x) returns the arc tangent of x. The arc tangent function is the inverse function of the tangent function and calculates the angle for a given tangent x. The result is an angle expressed in radians. To convert from radians to degrees, use the DEGREES function.
What is atan in Excel?
The Excel ATAN function returns the inverse tangent or arc-tangent of a number. In geometric terms, the function returns the angle of a right-triangle given the ratio of its opposite side over its adjacent side. The ATAN function is the inverse of the TAN function.
Does Photomath do trig?
Test or practice your trig skills on your way to the top of your math class. Use Photomath to check your answers or to help you work through steps when you’re stuck.
What does atan return?
ATAN returns the angle in radians. To convert the result from radians to degrees, multiply the result by 180/PI() or use the DEGREES function.
What is the meaning of atan?

How do I use atan in Excel?
This article describes the formula syntax and usage of the ATAN function in Microsoft Excel….Example.
| Formula | Description | Result |
|---|---|---|
| =ATAN(1)*180/PI() | Arctangent of 1 in degrees | 45 |
| =DEGREES(ATAN(1)) | Arctangent of 1 in degrees | 45 |
What is the difference between atan and ATAN2?
The atan() and atan2() functions calculate the arctangent of x and y/x , respectively. The atan() function returns a value in the range -π/2 to π/2 radians. The atan2() function returns a value in the range -π to π radians.
What is the difference between atan and ATAN2 in Excel?
Difference Between ATAN and ATAN2 For points in the second and third quadrants of the coordinate system, the ATAN function will return the angle relative to the negative x-axis direction. The ATAN2 function, by comparison, returns the angle relative to the positive x-axis which is the standard for measuring angles.
Why is atan2 used?
atan2(y,x) is generally used if you want to convert cartesian coordinates to polar coordinates. It will give you the angle, while sqrt(x*x+y*y) or, if available, hypot(y,x) will give you the size. atan(x) is simply the inverse of tan.
