" 6) "del" G Gifi "theta" an "cos theta=sin theta" is "4" is "2tan^(2)theta+sin^(2)theta+1=

If tan theta = 3/4, cos^(2) theta - sin^(2) theta = _______

If cos theta+cos^(2)theta=1 then sin^(2)theta+2sin^(2)theta+sin^(2)theta=

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) .

If sin theta=cos theta then 2tan theta+cos^(2)theta=

Show that none of the following is an identity: (i) cos^(2) theta + cos theta =1 " " (ii) sin^(2) theta + sin theta =2 " " (iii) tan^(2) theta + sin theta = cos^(2) theta

If cos^2theta-sin^2 theta = 1/2 . Then tan theta =

(cos theta-sin theta) / (cos theta + sin theta) = sec2 theta-tan2 theta

If 3cos theta-4sin theta=2cos theta+sin theta then find tan theta

If 3cos theta-4sin theta=2cos theta+sin theta, find tan theta.
