tan(pi2)

<-- Enter angle or number for inverse functions. Enter PI for π


Calculate tan(π2)
Since our angle is greater than 3π/2 and less than or equal to 2π radians, it is located in Quadrant IV
In the fourth quadrant, the values for cos are positive only.

360 is an obtuse angle since it is greater than 90°

tan(π2) = 2.9E-14

In Microsoft Excel or , you write this function as =TAN(PI()2)
