`cos theta+sin theta=1` then `theta`=

(sin3 theta+cos3 theta)/(cos theta-sin theta)=1+2xx sin2 theta

(1+cos theta+sin theta)/(1+cos theta-sin theta)=(1+sin theta)/(cos theta)

Prove each of the following identities : (i) (1+ cos theta + sin theta)/(1+ cos theta - sin theta) =(1+ sin theta)/(cos theta) (ii) (sin theta + 1- cos theta)/(cos theta - 1 + sin theta) = (1+ sin theta)/(cos theta)

cos theta/(1+sin theta)=(1-sin theta)/cos theta

If x=(2sin theta)/(1+cos theta+sin theta), then prove that (1-cos theta+sin theta)/(1+sin theta) is equal to x

(1-sin theta)/(cos theta)-(cos theta)/(1+sin theta)=2tan theta

The value of theta when sqrt3 cos theta+sin theta=1(0^theta le theta le 90^@) , is : theta का मान ज्ञात करें जब sqrt3 cos theta+sin theta=1(0^theta le theta le 90^@) है |

(1 + cos theta + sin theta) / (1 + cos theta-sin theta) = (1 + sin theta) / (cos theta)

Prove that (1)/(2){(sin theta)/(1+cos theta)+(1+cos theta)/(sin theta)}=(1)/(sin theta)
