`5costheta+12sintheta` का महत्तम मान . . . . . . . . . है |

5costheta + 2sintheta=2 , given tan68^(@) 12' = 5/2

If theta be positive acute angle and 5 costheta+12sintheta=13 , then the value of costheta is

Sintheta + Costheta = 2 Sintheta - Costheta = ?

Prove that all lines represented by the equation (2costheta+3sintheta)x+(3costheta-5sintheta)y=5costheta-2sintheta …(1) pass through a fixed point and its reflection in the line x+y=sqrt2 ? Prove that all lines through reflection point can be represented by the equation (2costheta+3sintheta)x+(3costheta-5sintheta)y= (sqrt2-1)(5costheta-2sintheta) ....(2)

12.5% of A = 55, What is the value of A? A का 12.5%= 55 है | A का मान क्या है?

Let P = [theta : sintheta – costheta = sqrt2 costheta) andQ= {theta : sintheta + costheta = 12 sintheta} be two sets. Then:

Let P = [theta : sintheta – costheta = sqrt2 costheta) andQ= {theta : sintheta + costheta = 12 sintheta} be two sets. Then:

If Sintheta + Costheta = 1 Sintheta - Costheta = ?

If A=[{:(costheta, sintheta),(-sintheta, costheta):}] , then A.A' is
