Use our tan(x) calculator to find the tangent of π/2 radian(s) - tan(pi/2 rad) - or the tangent of any angle in degrees and in radians.
a unit of plane angular measurement that is equal to the angle at the center of a circle subtended by an arc whose length equals the radius or approximately 180°/π ~ 57.3 degrees. secant the length of the hypotenuse divided by the length of the adjacent side.
The value of tan pi/2 can be calculated by constructing an angle of π/2 radians with the x-axis, and then finding the coordinates of the corresponding point (0, 1) on the unit circle. The value of tan pi/2 is equal to the y-coordinate(1) divided by the x-coordinate (0). ∴ tan pi/2 = not defined
Algebra. Evaluate tan (pi/2) tan (π 2) tan (π 2) Rewrite tan(π 2) tan (π 2) in terms of sines and cosines. sin(π 2) cos(π 2) sin (π 2) cos (π 2) The exact value of cos(π 2) cos (π 2) is 0 0. sin(π 2) 0 sin (π 2) 0. The expression contains a division by 0 0. The expression is undefined.
