sin^2+cos^2 theta = 1. can we take sin= 1-cos. because root of sin^2 theta +root cos^2 theta = root 1...and 1×1 is 1 so...root 1 is 1

NO U CANNOT UNDER ROOTS DO NOT WORK LIKE THIS
HERE IS THE CONTRADICTION TO UR ANSWER
LET SAY
SIN THETA =1 - COS THETA( FOR EVERY CASE )
THEREFORE
SIN THETA +COS THETA =1
THEN BY IDENTITY WE KNOW
sin^2+cos^2 theta = 1
SUBSTITUTING VALUE OF 1
sin^2+cos^2 theta = sin theta +cos theta
which cannot be true for every case
