Course Outcomes:
• Use partial derivatives to calculate rates of change of multivariate functions.
• Analyze position, velocity, and acceleration in two or three dimensions using the calculus of vector valued functions.
• Trace the curves which are useful in applications of integration in finding the length, area and volume.
• Recognize and solve first-order ordinary differential equations, model simple electrical circuits, projectile motion and Newton’s law of cooling and laws of decay and growth, and
• Use matrices, determinants and techniques for solving systems of linear equations in the different areas of Linear Algebra.
Scheme of examination:
• Two full questions (with a maximum of four sub questions) of twenty marks each to be set from each module. Each question should cover all contents of the respective module.
• Students have to answer five full questions choosing one full question from each module.
