MR. RAJU ROY earned his Bachelor of Science (Honors) degree in Mathematics and M.Sc. in Applied Mathematics from Khulna University, Bangladesh, in 2011 and in 2013, respectively. Mr. Roy, as was his wish, joined the mathematics discipline at Khulna University on January 2, 2017. In 2018 and in 2023, he was promoted to assistant professor and associate professor of the mathematics discipline of Khulna University. Prior to joining Khulna University, his academic expedition commenced on April 26, 2014, as a lecturer with the mathematics and statistics discipline of Jashore University of Science and Technology (JUST).

Transcending his teaching, Mr. Roy is deeply engaged in research. His research interests span several critical areas: probability theory, stochastic analysis, statistical machine learning, and mathematical finance.

Differential Calculus

The course intends to develop an understanding of some of the important aspects of calculus. This is one of the core courses in the stream of mathematics. Generally, calculus is divided into two main streams, one is Differential calculus and the other is Integral calculus. The part of calculus concerned with finding tangent lines and rates of change is called differential calculus. This course provides the fundamental knowledge of limit, continuity, and the instantaneous rate of change of one quantity with respect to another quantity. This course also deals with some important expansion of functions and the extreme value problems which are very important for solving some real-life applications of mathematics.

Advanced Calculus

Advanced calculus intends to develop an understanding of some of the multivariate tools of calculus. This course provides advanced knowledge of the function of several variables, domain, range, level curves, level surface, contour plot, limit, continuity, partial derivatives, and multiple integrals. It also deals with some real-life optimization problems related to multivariate calculus. This course plays a vital role in the field of applied mathematics.
