Vectors in Two or Three Dimensions (Modular Mathematics Series)

Vectors in 2 or three Dimensions offers an creation to vectors from their very fundamentals. the writer has approached the topic from a geometric point of view and even if functions to mechanics may be mentioned and methods from linear algebra hired, it's the geometric view that's emphasized throughout.

Properties of vectors are at first brought ahead of relocating directly to vector algebra and transformation geometry. Vector calculus as a method of learning curves and surfaces in three dimensions and the idea that of isometry are brought later, supplying a stepping stone to extra complicated theories.

* Adopts a geometrical approach
* Develops steadily, construction from fundamentals to the idea that of isometry and vector calculus
* Assumes almost no past knowledge
* a variety of labored examples, routines and problem questions
