" 40.यदि "q cos theta=sqrt(q^(2)-p^(2))" ,तो सिद्ध करें कि "q sin theta=p

if : p*cos theta=sqrt(p^(2)+q^(2)).sin theta, "then" : q * sin theta=

If sin theta= (p)/(sqrt(p^(2)+q^(2))) then prove that qsin theta=p cos theta

If cos theta=(2p)/(p^(2)+1) , then sin theta is equal to: यदि cos theta= (2p)/ (p^(2)+ 1) , है तो sin theta बराबर है:

If cos theta=(2p)/(p^2+1) , then sin theta is equal to : यदि cos theta=(2p)/(p^2+1) है,तो sin theta का मान किसके बराबर होगा?

ABCD is a trapezium such that AB and CD are parallel and BC bot CD . If angleADB = theta, BC = p and CD = q , then AB is equal to (a) ((p^(2)+q^(2))sin theta)/(p cos theta +q sin theta) (b) (p ^(2) + q ^(2)cos theta)/(p cos theta +q sin theta) (c) (p ^(2)+ q^(2))/(p^(2)cos theta +q^(2) sin theta) (d) ((p^(2) +q^(2))sin theta)/((p cos theta + sin theta)^(2))

Let P = {theta , sin theta - cos theta = sqrt(2)cos theta} and Q = {theta , sin theta + cos theta = sqrt(2) sin theta) be two sets. Then

If sin theta=(p^2-1)/(p^2+1) , then cos theta is equal to : यदि sin theta= (p^2-1)/(p^2+1) है, तो cos theta का मान है :

ABCD is a trapezium such that AB|CD and CB is perpendicular to them.If /_ADB=theta,BC=p, and CD=q, show that AB=((p^(2)+q^(2))sin theta)/(p cos theta+q sin theta)
