" 38.यदि "sin theta=(m)/(sqrt(m^(2)+n^(2)))." सिद करे कि "m sin theta+n cos theta=sqrt(m^(2)+n^(2))

5. sin m theta=sin n theta

cos m theta-sin n theta=0

cos m theta=sin n theta then theta=

If tan theta=(m)/(n) , show that (m sin theta-n cos theta)/(m sin theta+n cos theta)=(m^(2)-n^(2))/(m^(2)+n^(2))

If sin theta = (2m n)/(m^(2) + n^(2)) , find the value of (sin theta cot theta)/(cos theta)

If tan theta=(m)/(n) then (m sin theta+n cos theta)/(m sin theta-n cos theta) =

If sec theta=(m+n)/(2sqrt(mn)) find sin theta

If tan theta=(m)/(n), then find the value of cos theta and sin theta.

If a cos theta+b sin theta=m and a sin theta-b cos theta=n, Prove that a^(2)+b^(2)=m^(2)+n^(2)

If a cos theta+b sin theta=m and a sin theta-b cos theta=n, prove that a^(2)+b^(2)=m^(2)+n^(2)
