do you have a calculator no so let me solve this problem it is so simple just you need to do some practice don't have a calculator no problem
LHS=cosA−sinA+1cosA+sinA−1

=sinA(cosA−sinA+1)sinA(cosA+sinA−1)

=sinAcosA−sin2A+sinAsinA(cosA+sinA−1)

=sinAcosA+sinA−(1−cos2A)sinA(cosA+sinA−1)

=sinA(cosA+1)−(1−cosA)(1+cosA)sinA(cosA+sinA−1)

=(1+cosA)(sinA+cosA−1)sinA(cosA+sinA−1)

=(1+cosA)(sinA+cosA−1)sinA(cosA+sinA−1)

=1sinA+cosAsinA answer

mark it as brainliest plzzzz
