SynopsisExperimentation is inevitable part of actualizing theories. To inculcate the mathematical aptitude, habit of experimentation and self learning, CBSE conducts Practical Exams along with theoretical exams.
CBSE Class 9th, Mathematics Lab Manual has been prepared strictly according to the CBSE guidelines to include Activities and Projects in accordance with the curriculum. All activities given in this manual are given in Lucid, Simple and interactive format.
The theory given with each activity is gives complete understanding of each Concept, Definition, Formula. The book serves as the step by step guide with elaborated theory, procedure, observations, calculations, error rectification, results, precautions and viva voce in the format to be followed in the laboratory. The book covers also covers all the projects listed in NCERT lab manual so that students will need not to refer any other book.
