Question

If P (a cos $theta$ , bsin $theta$ ) is a point on an ellipse $fraction numerator x to the power of 2 end exponent over denominator a to the power of 2 end exponent end fraction plus fraction numerator y to the power of 2 end exponent over denominator b to the power of 2 end exponent end fraction equals 1$ , then ' $theta$ ' is –

Angle of OP line from positive direction of x-axis (O is origin)
Angle of OQ line from positive direction of x-axis [when Q is (a cos $θ$ , a sin $θ$ )]
It depends on the point p
None of the above

The correct answer is: Angle of OQ line from positive direction of x-axis [when Q is (a cos $theta$ , a sin $theta$ )]
