WebHere vector a is shown to be 2.5 times a unit vector. Notice they still point in the same direction: In 2 Dimensions. Unit vectors can be used in 2 dimensions: Here we show that the vector a is made up of 2 "x" unit vectors and 1.3 "y" unit vectors. In 3 Dimensions. Likewise we can use unit vectors in three (or more!) dimensions: WebThe formula for magnitude of a vector is: Example 01: Find the magnitude of the vector . In this example we have and so the magnitude is: Example 02: Find the magnitude of the vector . Solution 2 : Dot product The formula for the dot product of vectors and is Two vectors are orthogonal to each other if their dot product is equal zero.

WebYou are thinking a^2 + b^2 = c^2, and you would be correct in thinking about it, but remember that c^2 is not the length of the hypotenuse. c is the length of the hypotenuse. However, because we can use unit vectors and trig identities we can merely equate the hypotenuse to the sum of the i and j vectors.
