Question

sec^2theta(1+ sin theta)(1-sin theta)=k,find the value of k

Answer 1

Sec2 theta (1+sin)(1-sin)=k
Sec2theta *1-sin2 theta =k
Sec2theta *cos2 theta =k
K=1

Hope it helps you dear.........

Answer 2

Hey


The question is :-


Sec²∅ ( 1 + Sin∅ ) ( 1 - Sin∅ ) = K


= Sec²∅ [ ( 1 ) ² - ( Sin∅ )² ]


= Sec²∅ ( 1 - sin²∅ )


= sec²0 * cos²∅


= 1 / cos²∅ * cos²∅


= 1


So ,


k = 1


thanks :)
