If tan theta=(b)/(a)" then show that "acos2 theta+b sin2 theta=a

If tan theta . =(b)/(a) then prove that acos 2 theta +b sin 2 theta =a

If tan theta=(b)/(a) then a cos 2 theta+b sin 2 theta=

If tan theta=(b)/(a), find the value of a cos2 theta+b sin2 theta

If tan theta=(b)/(a), then find the value of a cos2 theta+b sin2 theta

If tantheta=b/a ,show that acos2theta+bsin2theta=a

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

If tan theta=(a)/(b) then b cos2 theta+a sin2 theta=

If tantheta=b/a Show that acos2theta+bsin2theta=a

If tan theta=(a)/(b), then b cos2 theta+a sin2 theta is equal to (a)a(b)b(c)(a)/(b)(d)(b)/(a)
