cot^2A = cosec^2A -1
cos^2A= 1-sin^2A
1/sec^2A = 1-1/ cosec^2A
1/sec^2A= (cosec^2A-1)/cosec^2A
sec^2A = cosec^2A/(cosec^2A-1)
also
sec^2A= 1+ tan^2A. so
1+tan^2A= cosec^2A/(cosec^2A -1)
tan^2A = cosec^2A/(cosec^2A-1) -1
tan^2A= 1/(cosec^2A-1)
cos^2A= 1-sin^2A
1/sec^2A = 1-1/ cosec^2A
1/sec^2A= (cosec^2A-1)/cosec^2A
sec^2A = cosec^2A/(cosec^2A-1)
also
sec^2A= 1+ tan^2A. so
1+tan^2A= cosec^2A/(cosec^2A -1)
tan^2A = cosec^2A/(cosec^2A-1) -1
tan^2A= 1/(cosec^2A-1)
