On the unit circle at 90 degrees the 90 degrees in radians is pi/2 and the coordinates for this are: (0,1).

The tan function = sin/cos. In the coordinate system x is cos and y is sin.

Therefore (0,1) ; cos=0, & sin=1 . Tan=sin/cos so tan of 90 degrees = 1/0.

The answer of tan(90) = undefined. There can not be a 0 in the denominator, because you can't devide by something with no quantity.

Something with no quantity is 0.

Or, on a limits point of view, it would be infinity.
