## Notes

### Variations:

• The value of a variable is not constant and keeps on changing. There are many quantities whose value varies as per the circumstances means variation in one quantity bringing in variation in the other quantity.

• If the values of two quantities depend on each other in such a way that a change in one causes a corresponding change in the other, then the two quantities are said to be in variation.
