Using the inverse of an exponential equation to find the logarithm
đŸ‘‰ Learn how to convert an exponential equation to a logarithmic equation. This is very important to learn because it not only helps us explain the definition of a logarithm but how it is related to the exponential function. Knowing how to convert between the different forms will help us i

Geometric Algebra in 3D - Fundamentals
In this video, we set up the geometric algebra of three dimensions, called G(3). We will see that the introduction of a third basis vector adds two extra bivectors and a trivector to our basis for G(3) compared to G(2). We'll see that geometric interpretations and computations are analogou

Integrating Exponential Functions with Substitution | Calculus 1 Exercises
We go over integrals of exponential functions (like e^2x) that require u-substitution (also called change of variable). We will also solve one integral simply requiring us to split up a fraction. Lots of exponential integral problems make for great practice! #apcalculus #calculus1 We int

Geometric Algebra in 3D - Bivector Addition
In this video, we will look at the algebraic and geometric interpretations of adding bivectors together in G(3). We will also show that all the bivectors in G(2) and G(3) can be factored as a wedging of two vectors, i.e. they are all 2-blades. This video has plenty of drawings and examples

Geometric Algebra - Duality and the Cross Product
In this video, we will introduce the concept of duality, involving a multiplication by the pseudoscalar. We will observe the geometric meaning of duality and also see that the cross product and wedge product are dual to one another, which means that the cross product is already contained w
