let theta =@
sec^4@ - sec^2@
=> sec^2@{sec^2@ -1 }
we know
sec^2@ - 1 =tan^2@
and sec^2@=1+tan^2@
use this here
(1+tan^2@)(tan^2@)
=> tan^4@+tan^2@= RHS
sec^4@ - sec^2@
=> sec^2@{sec^2@ -1 }
we know
sec^2@ - 1 =tan^2@
and sec^2@=1+tan^2@
use this here
(1+tan^2@)(tan^2@)
=> tan^4@+tan^2@= RHS
moyal123bhavya:
1+tan^2@ = Cot^2@ ....is that any formula???
no it is not any formula
Thnku
1+sec^2@ = Cosec^2@ ......is that??
