In Bangladesh, many students of upper classes try to earn some money by tution of students from lower classes. Basically almost all of our families canbt afford enough to support for study cost after supporting their family. So students try to earn some money beside study so that their family pressure for money reduces. And tution of students from lower class is the main source for a student to earn some money beside his study.
I also try to earn some money from tution. I have a student who is now seeking his HSC (Higher School Certificate) certificate from science department. His name is Md. Rifat Hasan. And he is a candidate of HSC exam in 2022. I basically try to make easy of his mathematics subject. I think none can teach other anything. A teacher can only make the topics easy and can ignite the thirst for knowing insude a student.
I took this photo when I was teaching him integral calculus. Basically calculus is started to teach after SSC examination in Bangladesh. Calculus is two types.
- Differential Calculus
- Integral Calculus
You must know about trigonometry well to learn calculus better. And first you have to study about differential calculus before trying integral calculus. If you don't know how to solve differential calculus, you can't solve integral calculus.
I have teach him differential calculus months ago. And now I am trying to tecach him integral calculus within a specific limit. And hence finding out the area enclosed by curves. You can't find out the area of a space enclosed by curve by as usual formula. You must take help of integration for this purpose. Differential calculus and integral calculus are just reverse process of one another. That's why many students face some problems when they try to solve it. They sometimes mix the processes to one another.
Thanks to all.
