The course include all chapters of class xii with proper understandable materials and basic as well as higher level education. All possible explanation with several problem to clear the concept of every topic. Assuring quality education. Mathematics is more or less required everywhere i.e. if anybody appears for competitive exams, for any jobs, or for further study purpose and much more. Student's will be provided with additional study materials to cope up the gap due to this pandemic. The study material would include MCQ based questions, short question etc. which are important for their practise and develop problem solving skills. Most of mathematical activity consists of discovering and proving properties of abstract objects. These objects are either abstractions from nature (such as natural numbers or lines), or (in modern mathematics) abstract entities of which certain properties, called axioms, are stipulated. A proof consists of a succession of applications of some deductive rules to already known results, including previously proved theorems, axioms and (in case of abstraction from nature) some basic properties that are considered as true starting points of the theory under consideration. The result of a proof is called a theorem. Mathematics is widely used in science for modeling phenomena. This enables the extraction of quantitative predictions from experimental laws. For example, the movement of planets can be predicted with high accuracy using Newton's law of gravitation combined with mathematical computation. The independence of mathematical truth from any experimentation implies that the accuracy of such predictions depends only on the adequacy of the model for describing the reality. So when some inaccurate predictions arise, it means that the model must be improved or changed, not that the mathematics is wrong. For example, the perihelion precession of Mercury cannot be explained by Newton's law of gravitation, but is accurately explained by Einstein's general relativity. This experimental validation of Einstein's theory shows that Newton's law of gravitation is only an approximation (which still is very accurate in everyday life).
