Tan of pi/2 + k*pi radians, for integer k, is not defined since tan = sin/cos and the cosine of these angles is 0. Since divsiion by 0 is not defined, the tan ratio is not defined.

Undefined.
both are equal... infinity is the representation of undefined.
the answer is UNDEFINED. It's because any number divided to 0 is undefined.
You do not. If you do, the expression is undefined: it has no value.
The answer is undefined.
90 degrees is one

tan90=Sin90/Cos90, sin90=1 and cos90=0 so 1/0 = undefined hence tan 90 is undifined

Assuming you mean -90 degrees, not radians: tan (-90) = [sin(-90)]/[cos(-90)] = (-1) / 0 You cannot divide by zero. tan (-90) is undefined/does not exist.
Undefined: You cannot divide by zero

tan x
Any vertical line is parallel to the y-axis in a co-ordinate plane.Therefore the angle of inclination is equal to 90 degrees.According to the formula , slope of a line = tanΘΘ = 90.Therefore slope = tan 90= sq.rt of {0/(4-4)}= sq.rt of 0/0= 0/0= undefined.
