Question

when ax is positive and ay is negative then what is angle​

Answer 1

Answer:

If the vector is pointing along the positive x-axis, then the angle is 0˚ (0 radians). If it is pointing along the negative x-axis, then the angle is 180˚ (π radians). If it points along the positive y-axis, the angle is 90˚ (π/2 radians), and if it points along the negative y-axis, the angle is 270˚ (3π/2 radians).
