Latest News. These are equivalent statements. Give it a try! If one angle has a tangent of 1, then the other angle must also have a tangent of 1. In this case, since they are both equal to each other, they MUST each have half of pi/2 = pi/4, it means inverse tangent in other words (arctan(x)=y) would also equal (tan(y)=x) so arc tan (1) would be tan^(-1). How to solve: What does \arctan 0 equal? The arctangent is the inverse tangent function. arctan 1 = ? It is used to calculate the inverse of a tangent. When the tangent of y is equal to x: tan y = x. To avoid confusion, most mathematicians define the range of arctan as (-pi/2, pi/2), which means that the answer to x = arctan(y) is always a value between -pi/2 and pi/2. When we see "arctan x", we understand it as "the angle whose tangent is x". Since. The ATAN function in Excel calculates the arctan (inverse of Tan) of a given number and returns the angle in radians between 0 and π. Arctan is inverse of tan. I am thinking of a number. So if you use a calculator to solve say arctan 0.55, out of the infinite number of possibilities it would return 28.81°, So the inverse of tan is arctan etc. In the figure above, click 'reset' and 'hide details'.
