Learn how to find the magnitude of a vector in standard form

The video tutorial explains how to find the magnitude of a vector using a right triangle approach. It starts by introducing the concept of a right triangle and then moves on to explain how to calculate the magnitude of a vector by finding the change in y and x components. The vector is expressed in component form, and the magnitude is calculated using the Pythagorean theorem. The tutorial concludes with a discussion on notation, specifically how the magnitude is represented using a double absolute value symbol.
