What should I choose Pure Maths in SPPU or Applied Maths in MSU. Which one is better option & what about their placements.
It is better than pure mathematics because it uses the formulas of pure maths and applies them in the real life. Applied maths tries to model predict, and explain things in the real world. Applied maths is easy for students who are strong with engineering concepts.
There are some fields of mathematics in which people do research which has applications today in fields like physics, chemistry, biology, finance, etc. Their motivations will be some real world problems and they will be using mathematical theories and tools or may altogether propose new mathematical theories to solve those real world problems just like Newton did few hundred years ago. These mathematicians also get immense pleasure.
Broadly speaking there is a very thin line between pure maths and applied maths these days. We simply call it MATHS. But to answer your question, MSc applied maths has more career opportunities than MSc pure maths. In applied maths you may get lot of corporate job opportunities.
