If the axes are rotated through an angle of 30o in the anti-clockwise direction, the coordinates of point (4,−2√3) with respect to new axes are
The origin of the co-ordinate axes is shifted to (-1,3) and the axes is rotated through an angle of 90∘ in anti-clockwise direction. If (a,b) is the new coordinates of (2,3) in the new coordinate system, then find the value of 2a2+3b2
Co-ordinate axes are rotated through an angle of 45∘ in the anti-Clockwise direction. Find the Co-Ordinates of (2,3) in new co-ordinate system.
The origin is shifted to (m,2) and the axes are rotated through an angle of 90∘ anti clockwise. The new co-ordinates of P(3,5) is (3,-2) . Find the value of m.
