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.
The answer is undefined.
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

undefined
tan90=Sin90/Cos90, sin90=1 and cos90=0 so 1/0 = undefined hence tan 90 is undifined
the answer is UNDEFINED. It's because any number divided to 0 is undefined.
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
tan x
Division by zero is undefined.
You do not. If you do, the expression is undefined: it has no value.
