About the Book: Laboratory Manual Mathematics Class IX
No theory can be proved without experimentation. Conclusions that are observed and verified in real time are authentic and easy to retain. CBSE conducts Practical Exams along with theoretical exam to test the scientific aptitude of students. CBSE Class 9th, Mathematics Lab Manual has been prepared strictly according to the guidelines. All the activities in this manual have been in simple, lucid and in an interactive manner. The theory given with each activity gives complete understanding of each concept, term, definition and formula, etc. Viva Voce questions given with each activity try to make concepts more clear in accordance with the curriculum. Along with the Activity, all the projects listed in NCERT Lab Manual have also been covered. The book serves as the step by step guide for conducting experiments in such a way that students will not need to refer any other book for explanations of the concepts.
