Question

Sin theta +cos theta =1 prove that tan + cot =1

Answer 1

Answer:

Sin theta +cos theta =1

sin theta + 1 - sin²theta = 1

sin²theta - sin theta = 0

sin theta(sin theta - 1) = 0

sin theta = 1

so

theta = 90°

tan theta + cot theta

tan90 + cot90

is not equal to 1

so there is some thing wrong in the question
