The ratio of the distance from the center to point 1 and the distance from point 1 to point 2 is given by (11ea7a51_6362_2f53_89bd_3f32ce3ea797_TB5259_11)/(11ea7a51_6362_2f52_89bd_231f3173e0f0_TB5259_11). This ratio is the largest because both the numerator and denominator are positive and the numerator is increasing at a greater rate than the denominator, due to the increasing angular velocity.
