Question

solve 1 + secA upon sec A is equals to sin square A

Answer 1

1+sec A=1secAI think it will help you

Answer 2

(1+secA)/secA=sin^2 (A)

1/secA +secA/secA =sin^2 (A)

cosA+1=sin^2 (A)

cosA+1-sin^2 (A)=0

cosA+cos^2 (A)=0

cosA (1+cosA)=0

cosA=0

cosA=pi/2

A=2npi+pi/2

A=2npi-pi/2npi

OR

1+cosA=0

cosA= -1

cos A=pi

A=2npi+pi

A=2npi-pi
