if `(2m + 1) sin theta = 2m(m + 1) cos theta`, then `sin theta =`

(m+2)sin theta+(2m-1)cos theta=2m+1 then tan theta is

If (m+2)sin theta+(2m-1)cos theta=2m+1 then

If (m+2) sin theta+(2m-1) cos theta=(2m+1) , then show that tan theta= =(4)/(3)or (2m)/(m^(2)-1) .

If m= sin ^(2) theta + cos ^(4)theta, then-

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

If u = (1 + cos theta) (1+ cos2 theta) - sin theta sin 2theta, v = sin theta (1 + cos2 theta) + sin 2 theta(1 + cos theta), "show that" u^(2) + v^(2) = 4(1 + cos theta) (1 + cos 2theta).

If cos m theta = sin n theta , then theta =

cos m theta=sin n theta then theta=

Find the A.M. between: ( cos theta + sin theta )^(2) and ( cos theta - sin theta)^(2)
