Hanley Rd, Suite St. Louis, MO We are open Saturday and Sunday! Subject optional. Email address: Your name:. Which of the following pairs of vectors are perpendicular?

Possible Answers:. Correct answer:. Explanation : Two vectors are perpendicular when their dot product equals to. Recall how to find the dot product of two vectors and The correct choice is. Report an Error. The correct choice is,. Recall that for a vector, The correct answer is then,. The correct answer is then,. Explanation : For two vectors, and to be parallel, , for some real number. Thus making the vector parallel,. Thus making the vector parallel. Solution to Question 6 From point D outside the circle, two tangent through D to the the circle of center C may be found see figure 1 below.

Finally, notice that these three new vectors are simply the three standard basis vectors for three dimensional space. So, we can take any vector and write it in terms of the standard basis vectors.

From this point on we will use the two notations interchangeably so make sure that you can deal with both notations. The theorem works for general vectors so we may as well do the proof for general vectors. Here is the work. Notes Quick Nav Download. You appear to be on a device with a "narrow" screen width i.
