**Class 11 Mathematical Methods MCQs Pdf **

Mathematics is the main language of physics. By using mathematical methods it becomes easier to describe, understand and apply the physical principles, if one has a good knowledge of mathematics. In the present physics syllabus we shall constantly use the techniques of algebra, trigonometry and geometry as well as vector algebra, differential calculus and integral calculus etc. In this Page we shall discuss the Class 11 Mathematical Methods MCQs.
