If: `cos^(-1) (sin theta) = sin^(-1) (cos theta)`, then: `theta`=

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

If (cos theta)/(1+sin theta)-(1-sin theta)/(cos theta)=2k then the value of k is :

cos theta/(1+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)

Prove that: (sin^(3) theta + cos^(3) theta)/(sin theta + cos theta) = 1-sin theta cos theta

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