Question

If sec²θ(1+sinθ) (1-sinθ)=k,then find the value of k

Answer 1

sec*2theta (1+ sin theta)(1-sin theta )
sec*2 theta (1-sin*2 theta )
sec*2 theta cos*2 theta
as sec is the reciprocal of cos so
k=1

Answer 2

sec^2#(1-sin^2#)
sec^2#.cos^2#=k
k=1
#= thetha cause thetha symbol is not given in keyboard
