MATHEMATICS-II (Mathematical Methods) for JNTUK - R16

Course Objectives: 1. The course is designed to equip the students with the necessary mathematical skills and techniques that are essential for an engineering course.
2. The skills derived from the course will help the student from a necessary base to develop analytic and design concepts.
3. Understand the most basic numerical methods to solve simultaneous linear equations.
Course Outcomes: At the end of the Course, Student will be able to: 1. Calculate a root of algebraic and transcendental equations. Explain relation between the finite difference operators.
2. Compute interpolating polynomial for the given data. 3. Solve ordinary differential equations numerically using Euler’s and RK method. 4. Find Fourier series and Fourier transforms for certain functions. 5. Identify/classify and solve the different types of partial differential equations.
