Question

sin theta by 1 minus cot theta + cos theta by 1 minus tan theta is equal to​

Answer 1

Step-by-step explanation:

expand tan and cot..

into cos and sin..

Answer 2

1. sin theta by 1 minus cot theta + cos theta by 1 minus 10 theta is equal to sin theta by 1 minus cos theta by sin theta + cos theta by 1 minus sin theta by cos theta is equal to sin theta by sin theta minus cos theta by sin theta + cos theta by cos theta minus sin theta by cos theta is equal to sin theta by sin theta minus cos theta into sin theta by 1 + cos theta by cos theta minus sin theta into cos theta by 1 is equal to sin square theta by sin theta minus cos theta + cos square theta by cos theta minus sin theta is equal to minus sin square theta + cos square theta by sin theta minus cos theta is equal to minus sin theta sin square theta + cos square theta by sin theta minus cos theta get cancelled therefore = cos theta+sin theta
