This module is designed for one-semester calculus course aimed at students majoring in science and engineering. A wide variety of topics, examples and problems are provided. This module can be used as an aided tool in teaching and learning multivariable calculus. This module consists of four chapters. Students are introduced to polar coordinates and vectors in Chapter 1. This chapter includes the 3-dimensional graph sketching and polar curve, allowing for a source of rich illustrations and exercises. The next chapter concentrate on vector-valued functions including discussions on arc length, curvature and motion in space. Chapter 3 covers partial derivative involving functions with more than one variable. The final chapter covers multiple...
