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

cos p theta=cos q theta,p!=q, thetn

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

If cosectheta=(p+q)/(p-q),then cot(pi,//4+theta//2)=

If sin theta+cos theta=p and sec theta+csc theta=q show that q(p^(2)-1)=2p

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