The basic purpose of this lab manual not only eases the approach of the Laboratory courses but also to provide the students appropriate guidance required for carrying out the experiments in math laboratories. All the experiments in this manual have been given to confirm to a systematic format that includes Theory, Material Required, Procedure, Observation, Result, Precautions, Viva Voce and Suggested Activities.
