Dot Product
This applet graphically and numerically shows the effects that the length of two vectors and the angle between them have on the dor product.
The Dot Product applet shows how the scalar dot product value of two vectors depends on both the vectors' lengths and the angle between them. It also demonstrates the dot product's property of rotational invariance. Editable equations are displayed, as are concept explanations and help text. The dot product is an essential building block in linear algebra and for doing almost any type of transformation or rendering in computer graphics.
