Whatever we have learnt, it is very important to produce in the exam, so that we can score the best scores/grades/marks.
1) Understand the concepts
2) Try to make some easy way to remember
For example: When you are learning Trigonometry,
In the below table, to remember first write the denominator as hypotenuse.
Then just write perpendicular in the numerator (in the first column i.e, Sin), then as base in the second one, I.e., cos. Finally in the tan first by second i.e, perpendicular/Base. So, we should try to have some clues so that we try to remember and do the sums with correct formulas
Sin | Cos | Tan | |||||||
Perpendicular/hypotenuse | Base/hypotenuse | Perpendicular/Base |
