Document Summary

Transformation of space . defines a vector d vector i scalar i scalars do not transform i vectors transform if change x. y . Z axis . then vector will change while a scalar not change vector unit. Cn . y , # ) vector : A a r position rector then axis r a a nor. C p , if change x. g. z neither vector: b. wso. :blasso doesn"t change , i is a scalar since r will change scalar axbxtaybytazbx-a. b. co it"s the component of.
