Code of Conduct during Field Work

(In the Hostel/Hotel)

Students should turn off their cell phones during lectures. Students are prohibited from engaging in other activities (such as texting, watching videos etc. during lectures. A register is marked at 10pm each night to ensure that every student is around. Going out at late hours is forbidden or prohibited except on emergency cases where a student took ill and had to be rushed to the nearest hospital. This is normally done with the consent of any of the instructors. All the rules and regulations for a successful field work as outlined by the field co-ordinator must be strictly adhered by both students and staff members.

 (On the Field)

Late coming to the field by the students is not allowed. Playing on the field while others are working will attract severe sanctions and in extreme cases, the students may be asked to return to school, this means automatic carry-over of the course to another year

Numerical Analysis I

Course Synopsis

This course is the first course in numerical analysis designed for students in mathematics, physical sciences, engineering, mineral and earth sciences. The focus of the course is to equip students with basic useful skills to solve numerically both theoretical and empirical problems leading to linear and nonlinear equations. Topics to be covered include numerical solution of algebraic and transcendental equations; curve fitting; error analysis; interpolation and approximation; zeros of non linear equations in one variable; system of linear equations; numerical differentiation and integration.
