This segment clarifies terms such as significant digits (last decimal digit), independent events (outcomes not affecting each other), and rational numbers. It also defines correlation as a measure of the relationship between two variables, and proportion as a statement of equality between two ratios.
The video explains that a trinomial is an algebraic expression with three terms, and an even number is exactly divisible by two. It introduces the concept of similar triangles when an angle and two corresponding sides are proportional. It also defines a sphere as a body where every point on its surface is equidistant from a central point.
This section covers Pascal's principle, stating that fluid pressure is the same in all directions. It defines a vacuum as a space devoid of matter with zero pressure. The video also mentions that 1 British Thermal Unit (BTU) is equivalent to 252 calories.
The concept of working capital, which are funds required for an enterprise to be a going concern, is discussed. The symmetric axiom in algebra (if A=B, then B=A) is illustrated. Depreciation recovery is defined as the present worth of all depreciation over an item's economic life.
This part identifies quadrants 1 and 3 as where the secant and cosecant of an angle have the same algebraic sign. It defines a theorem, in relation to the volume of a circular cylinder, as a statement that can be proven. An axiom is noted as a part of a theorem assumed to be true. The SI unit of electrical conductance is identified as the Siemens.
