Question

I cant understand the numericals

Answer 1

1. Try to absorb the contents of a tutorial in small chunks. Pause and ponder over what you read. Visualize and scribble on a paper
2. Understand the derivation of important equations - Often the derivation itself gives great clarity around the topic and the numerical problems you will attempt.
3. Learn to deconstruct a numerical problem. Making neat diagrams and putting all the available information around it can accelerate you towards writing the correct equations and therefore the answers
4. Be disciplined about not "rushing through" when solving a numerical problem. In other words, do not jump steps while doing a problem.
5. Get the basic understanding of maths, particular integral and differential calculus, in place. It will be required for solving numerical problems
6. Revisit the chapter after you have completed numerical. You'll find your understanding of the topic improve several notches
7. Try attempting numerical problems again

Most importantly, be patient, persist and practice
