Answer 1

LHS=sinθ−cosθ+1sinθ+cosθ−1

=cosθ(sinθ−cosθ+1)cosθ(sinθ+cosθ−1)

=cosθ(sinθ−cosθ+1)cosθsinθ+cos2θ−cosθ

=cosθ(sinθ−cosθ+1)cosθsinθ−cosθ+1−sin2θ

=cosθ(sinθ−cosθ+1)1−sin2θ−cosθ+sinθcosθ

=cosθ(sinθ−cosθ+1)(1−sinθ)(1+sinθ)−cosθ(1−sinθ)

=cosθ(sinθ−cosθ+1)(1−sinθ)(1+sinθ−cosθ)

=cosθ1−sinθ

=cosθcosθ1−sinθcosθ

=11cosθ−sinθcosθ

=1secθ−tanθ=RHS

it will help u

plzzz make it brainliest
