Question

How to solve a function in maths? In a way that it didn’t form a function?

Answer 1

Mathematical functions are the first things you need to understand to master calculus. Most people that take this subject learn how to solve problems like a machine, but do not grasp this essential concept.
So, first things first. What are we talking about here? In calculus, we study quantities that change.
Quantities that change are called variables.
For example, temperature is a variable. It changes throughout the day. The speed you drive your car is a variable.
In fact, almost everything in nature is a variable.
This is why calculus can be so fascinating and useful. It can be applied to any quantity that changes.
In nature, we not only see quantities that change. We also see that some quantities are connected to one another in some way.
For example, we see that it is hotter during the day. During the night it is colder. To understand better this connection between things we invented mathematical functions.
