Hi Vijaya Ragavan:

 

Tan90 = sin90/cos90.

 

And we know cos90 = 0.

So tanx, as x→90 will tend to infinity.

 

As such tan90 is not defined, because cos90 is in the denominator (which is 0) No fraction should have 0 in the denominator.

 

Best Regards,

Ashwin (IIT Madras).

it is undefined because it is a number divided by zero
