Math Review
Linear equations with unknown coefficients: Sal solves the equations ax+3x=bx+5 and a(5-x)=bx-8 for x. Note that these equations include other unknowns (a and b) but we solve them for x.
Interpreting units in formulas: Sal finds an appropriate measurement unit for Power given the formula P=W/t where P is Power, W is Work, and t is Time.
Intercepts from a table: Sal finds the y-intercept of the graph of a linear function given a table of values.
Some introductory physics:
These are fairly short videos that put art history in a broader, albeit simplistic context:
And yes, the narrator is kind of annoying.
