" 14.Show that "(sin theta+cos theta)/(sin theta-cos theta)+(sin theta-cos theta)/(sin theta+cos theta)=(2)/(sin^(2)theta-cos^(2)theta)=(2)/(2sin^(2)theta-1)

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

(sin theta-cos theta)^(2)*(sin theta+cos theta)^(2)=

Prove each of the following identities : (sin theta + cos theta)/(sin theta - cos theta) + (sin theta - cos theta)/(sin theta + cos theta) = (2) /((sin^(2) theta - cos^(2) theta)) = (2) /((2sin^(2) theta -1))

Prove that (sin theta+cos theta)/(sin theta- cos theta) + (sin theta - cos theta)/(sin theta + cos theta) = ( 2sec^(2) theta)/(tan^(2) theta -1) .

cos theta+sin theta=cos2 theta+sin2 theta

Prove that : (1+sin2 theta-cos 2theta)/(sin theta+cos theta)=2sin theta

((sin theta+cos theta)^(2)-1)/(sin theta*cos theta)

(1+sin2 theta-cos2 theta)/(1+sin2 theta+cos2 theta)=tan theta

Show that :((cos theta-cos3 theta)(sin8 theta+sin2 theta))/((sin5 theta-sin theta)(cos4 theta-cos6 theta))=1

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