Inverse tangent is usually abbreviated as "arctan" or "atan", as in the following equation: a r c t a n ( y) = a t a n ( y) arctan (y)=atan (y) arctan(y) = atan(y) Where it is the inverse of tangent, or: x = a r c t a n ( y) y = t a n ( x) x=arctan (y)\\y=tan (x) x = arctan(y) y = tan(x)

04.11.2015 · The answer is − π 4 Explanation: Alright, archtan / tan−1(x) is the inverse of tangent. Tan is sin cos. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4. Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan (-1) equal.

The inverse tangent of a number is the angle in radians, whose tangent is the specified number. The resulting angle ranges from -pi/2 to pi/2. Fortunately, Excel provides us a way to calculate the inverse tangent of a number using the ATAN function. Figure 1. Final result: Inverse tangent Syntax of ATAN =ATAN(number)

Tangent calculator Arctangent definition. The arctangent function is the inverse function of y = tan(x). arctan(y) = tan-1 (y) = x+ kπ. For every. k = {...,-2,-1,0,1,2,...} For example, If the tangent of 45° is 1: tan(45°) = 1. Then the arctangent of 1 is 45°: arctan(1) = tan-1 (1) = 45° Arctangent table

To find the inverse tangent, we have to find the angle that would result in the desired number if we obtain its tangent. For example, if we want to find the inverse tangent of 1, we have to ask ourselves “what angle has a tangent of 1?” The answer is 45°, so we conclude that the inverse tangent of 1 is 45°.

In the tan function, value of angle θ is taken to give the ratio opposite/adjacent. However, inverse tan function takes the ratio opposite/adjacent and gives angle θ . tan -1 (opposite/adjacent) = θ Inverse tangent symbol Inverse tangent is represented as tan-1 or arctan . # Inverse tangent rule The inverse tan rule is given as: y = tan-1 (x)

Tan Inverse Formula Tan (A)= Opposite Side / Adjacent Side A = Tan -1 (Opposite Side/Adjacent Side) where A is an angle For example, if in a triangle, opposite side to angle A is 1 and the adjacent side is √3 So tan -1 (1/ √ 3) = A As we know, tan 30 = 1/ √3 Therefore, tan -1 (tan 30) = A or A = 30 degrees Solved Examples

To find the inverse of tangent you can use its following formula: y = t a n ( x) | x = a r c t a n ( y) Also, you could use the arctan calculator for calculating inverse tangent, instead of using the above formula. Example If the tangent of 45 o is equal to 1 So a r c t a n 1 = t a n − 1 ( 1) = 45 ° 45 ° = 45 ∗ π / 180 = 1.548 r a d

The inverse of a tangent function is arctan or inverse tan or atan. i.e., tan-1 = arctan. The value of tangent function varies from -∞ to +∞.
