  1. To become familiar with a range of well-known sequences and shows with a growing understanding of how they behave in new series.
  2. To help the students understand the notion of differential equations and multivariable calculus.
  3. To provide the students with the basic concepts and tools appropriate for Intermediate to Advanced levels in mathematics to build confidence and competence for students to tackle diverse real-world issues and their solutions.

Sequences Series, Sequences, and Mean value theories: Sequences and Series: Convergences as well as divergence tests – Ratio test – Tests for comparison Integral test – Cauchy’s root test – Alternate series- Leibnitz’s Rule. Mean Value Theorems (without proofs) of Rolle Lagrange’s Mean Value Theorem Cauchy’s Mean Value Theorem Maclaurin and Taylor’s theorems, with problems, the remainders, and their applications to this theorem.
