Arctan Calculator
Calculate arctangent values easily with our online Arctan Calculator.
What is the Arctan Calculator & How does it work?
The arctangent, also known as the inverse tangent, is a trigonometric function that returns the angle whose tangent is a given number. It is commonly used in various fields such as physics, engineering, and navigation to determine angles from ratios of sides in right triangles.
The arctangent function takes a single argument, which is the ratio of the opposite side to the adjacent side in a right triangle. The result is an angle measured in radians or degrees, depending on the context.

theta = arctan(frac{opposite}{adjacent})
theta = angle in radians
opposite = length of the opposite side
adjacent = length of the adjacent side
opposite = length of the opposite side
adjacent = length of the adjacent side

Frequently Asked Questions
How do I use the arctangent calculator?
Enter the ratio of the opposite side to the adjacent side in a right triangle into the calculator to find the angle.
What does arctan return?
The arctan function returns the angle whose tangent is the given number, measured in radians or degrees.
Can I use this calculator for any triangle?
This calculator is specifically for right triangles. For non-right triangles, you may need to use other trigonometric functions.
What is the range of the arctan function?
The arctan function returns values between -90 and 90 degrees (or -Ο/2 and Ο/2 radians).
How do I convert the result from radians to degrees?
Multiply the radian value by 180/Ο to convert it to degrees.
Is this calculator accurate for all inputs?
Yes, the arctan calculator provides accurate results for a wide range of valid inputs.
Can I use this calculator for complex numbers?
This arctan calculator is designed for real numbers. For complex numbers, you may need specialized software or calculators.
