Dot Product with GeoGebra

This guide walks you through the steps to compute the dot product of two vectors in GeoGebra.

Begin by generating two vectors from the origin, labeled u and v.

If creating a vector seems daunting, don't worry. I've covered the basics in another tutorial on crafting a vector with GeoGebra.

Open a fresh GeoGebra sheet and input Dot(u,v)

Replace u and v with the names of your freshly minted vectors.

Hit enter, and voilà!

GeoGebra effortlessly computes the dot product of your vectors.

In our case, the dot product turns out to be 10.

Why bother with the dot product? Beyond its vector origins, the dot product boils down to a single, insightful number. It's dubbed "scalar" because of this. A dot product of zero? That means your vectors are orthogonal, intersecting at a crisp 90° angle. Curious for more? Dive deeper into the dot product here.

You can also summon the dot product on GeoGebra with a straightforward u*v

The outcome remains consistent.
