well..........i dont know any links about that.

But what i can say for sure the modulus of something is always positive.

By the way which chapter are you dealing with??

elemis:
I am assuming you are referring to the modulus of a vector.

If was the coordinates of a vector A.

Then A would be something like the diagram below.

The modulus helps us determine the magnitude of a vector. The modulus is calculated by :

This is basically applying Pythagoras's Theorem to find the length of a hypotenuse.

NOTE : The modulus is ALWAYS POSITIVE. If you get a negative answer then you have done something wrong.

If it is in negative, u can also find the determinant of it.  ;D
