If `costheta/p=sintheta/q`, then `p/(sec2theta) + q/(cosec\ 2theta)` is equal to (i) `p` (ii)`q` (iii)`pq` (iv) none of these

If (cos theta)/(p)=(sin theta)/(q), then (p)/(sec2 theta)+(q)/(cos ec2 theta) is equal to (i) p( ii) q( iii) pq (iv) none of these

If tan theta = p/q then (p sin theta - q cos theta)/(p sin theta + q cos theta)=

If tan theta = p/q then (p sin theta - q cos theta)/(p sin theta + q cos theta)=

If cos ec theta=(p+q)/(p-q)(pq>0,p!=q), then |cot((pi)/(4)+(theta)/(2))| is equal to

If sin theta+cos theta=p and sec theta+cos ec theta=q find q(p^(2)-1)=

If cos theta + sin theta = p and sec theta + cosec theta = q , prove that q (p^(2) - 1) = 2p .

a cot theta+b cosec theta=p and b cot theta+ a cosec theta=q then p^(2)-q^(2) is equal to

If tan theta=(p)/(q) then (p sin theta-q cos theta)/(p sin theta+q cos theta)=

If tan theta=(p)/(q) then (p sin theta-q cos theta)/(p sin tehta+q cos theta)=
