Rajat, u hav written that
 
cotB+cotC>= 2/sq root (tanB tanC)
 
and this is valid only if tanB  and tanC are well defined.....and when B or C tends to 90degrees,  u hav one of them to be undefined....

thats exactly what i am saying .if tanB or tanC tend to be undefined (please call it  infinity), 2/(tanB.tanC)^1/2 will tend to be zero because
2/infinty =0 .
light travels the fastest ??? NO
wherever light goes it always finds that darkness has already got there
