Rectangular coordinate axes

If vec a makes equal angles with the coordinate axes and has magnitude 3, find the angle between vec a and each of the three coordinate axes.

If veca makes equal angles with the coordinate axes and has magnitude 3,find the angle between veca and each of the three coordinate axes.

The side of a square ABCD is 'a' units A,B,C,D are in the anti-clockwise order AB and AD are coordinate axes. Then coordinates of C are

If the foci of an ellipse are (0,+-1) and the minor axis is of unit length,then find the equation of the ellipse.The axes of ellipse are the coordinate axes.

If the foci of an ellipse are (0,+-1) and the minor axis is of unit length, then find the equation of the ellipse. The axes of ellipse are the coordinate axes.
