Tan Inverse Calculator
Calculate the inverse tangent of any value with our online Tan Inverse Calculator.
What is the Tan Inverse Calculator & How does it work?
The inverse tangent, also known as arctangent or tan-1, is a mathematical function that returns the angle whose tangent is a given number. This calculator helps you find the angle in radians or degrees for any real number input.The inverse tangent function is widely used in trigonometry and engineering to determine angles from known side lengths in right triangles. It is particularly useful in fields such as physics, navigation, and computer graphics.

Frequently Asked Questions
How do I use the inverse tangent calculator?
Enter the tangent value into the calculator, then select whether you want the result in radians or degrees.
What is the inverse tangent function used for?
The inverse tangent function is used to determine angles from known side lengths in right triangles, and it’s useful in fields like physics, navigation, and engineering.
Can I use this calculator for negative values?
Yes, you can input any real number, including negative values, into the inverse tangent calculator to find the corresponding angle.
What is the range of the inverse tangent function?
The range of the inverse tangent function is from -Ο/2 to Ο/2 radians (or -90 to 90 degrees).
How do I convert the result from radians to degrees?
To convert radians to degrees, multiply the radian value by 180/Ο.
What is the difference between tangent and inverse tangent?
Tangent gives the ratio of opposite to adjacent sides in a right triangle, while inverse tangent returns the angle whose tangent is a given number.
Is this calculator accurate for all inputs?
