Physic is my major and there are some electives of math units now...I am in trouble with choosing one pair from these two options: 【MATLAB】+【Advanced ordinary differential equations】 or 【Algebra and number theory】+【Real analysis】 can anyone tell me which one is better for me if I plain to...

there is a gyro... put it on an electronic scales which has a smooth surface...it shows the weight is M. then, let it rotate... keep increasing the angular velocity... will the weight display increase? or else?
