Anti-Shapeshifters - Easy Visual Logs and Hyperbolic Trig

Explore visual logarithms and hyperbolic trigonometry in this 33-minute video lecture. Delve into fascinating mathematical concepts, starting with a Rubik's cube demonstration and progressing through area calculations, infinite series sums, and logarithmic bases. Discover the visual representation of logarithms and investigate the properties of circles in different coordinate systems. Examine the relationship between exponential and hyperbolic functions, culminating in a proof of the equation e^a = cosh(a) + sinh(a). Gain insights into the connections between these mathematical ideas and their applications in physics, including Lorentz transformations in special relativity.
