Question

1. prove that 1 tan²A = sec² A
​

Answer 1

Answer:

there must be 1+ tan2 A= sec2 A please correct yourself then post it.

Answer 2

Step-by-step explanation:

cos^( x ) + sin^ ( x ) = 1

Divide both side by cos^ ( x ), We get,

cos^ ( x ) / cos^ ( x ) + sin^ (x)/ sin^ ( x) = 1/ cos^ (x)

which simplifies then,

1 + tan^( x ) = sec^ ( x )

Hence proved.....
