i m confused in these topics which is defecting my maths n phy..

In which part of it? Where is the clarification needed?

 

[♫Prince Shah♫]

from first i m totally confused

I'm guessing you will be sitting for your O'Levels.

Well, differentiation...if it is to be simply put....is actually the gradient. In other words when we express it in terms of (dy/dx) it is said to be the rate of change in y with respect to x (the rate of change of one quantity with respect to another). For example, let's take (ds/dt), where s stands for distance and t for time. This means it is the rate of change in distance with respect to time. In other words, it is the speed.

If you come to the rules of differentiation:
E.g. y=3x^2
dy/dx=6x
Did you see that? The power of x is multiplied with its co-efficient.

I am sorry....made a mistake....you will be sitting for your A Levels. It's all the same anyway.

wat abt integrtn???

 

[Shaoli Hassan]

Yes, itegration.....that is the exact opposite to differentiation. As I said when y=3x^2, dy/dx=6x.
For integration,if y=6x, the result of integrating it would be 3x^2. Simply put....for integration, you have to add 1 to the power of x in the function and also divide the function by the final power of x.

Just tell me one thing....did you habe additional mathematics in your O'Levels?

nope

 

[Shaoli Hassan]

that explains why you are confused. Always glad to help.....btw, what do you mean by when to use it?

I guess I realised what you meant.....you can use integration when let's say the gradient of a curve is provided. You can integrate the gradient to find the equation for the curve. Remember, that if it is an indefinite integration you have to write "+c" at the end of your result. If the integration is definite then you don't have to write it.
