1.20 câx Calculate vector magnitude with dot products. (Section 2.9 and Hw 1.19) Show how the vector dot-product can be used to show that the magnitude of the vector câx (c is a positive or negative number and ax is a unit vector) can be written solely in terms of c (without âx). Result: |câx| +√c²= abs(c) - c² * = =
