Study Notes

Mathematical Concepts

  • A regular polygon with 27 diagonals is a nonagon.
  • Stirling's Approximation is a formula used to compute the value of n factorial when n is a large number.
  • The formula for computing the value of n factorial is n!.
  • The derivative of a function is the rate of change of the function with respect to its input.
  • A co-logarithm is the logarithm of the reciprocal of a number.
  • Two angles whose sum is 360° are called explementary angles.
  • A deferred annuity is a series of equal payments occurring at equal intervals of time where the first payment is made after several periods, after the beginning of the payment.
  • Fair value is the amount of a property that a willing buyer would pay to a willing seller, with neither being under any compulsion to buy or sell.
  • An algorithm is a series of sequential steps for carrying out a desired procedure to solve a problem.
  • Trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of triangles.
  • An asymptote is a straight line that a curve approaches closely but never meets or touches.
  • A median is a line segment from a vertex of a triangle to the midpoint of the opposite side.
  • An altitude is a perpendicular segment from a vertex of a triangle to the line containing the opposite side.
  • Are is an SI unit of area equal to 100 square meters.
  • Angle of elevation is the angle that the line of sight to an object makes with the horizontal when the object is above the eye of the observer.

Engineering Economy

  • Escalatory clauses are provisions in contracts that indicate the possible adjustment of material cost and labor cost.
  • Appraisal is the process of determining the value of certain property for specific reasons.
  • Consumer goods and services are products or services that are directly used by people to satisfy their wants.
  • EOQ (Economic Order Quantity) is the order quantity that minimizes the inventory cost per unit time.

Chemistry

  • Organic substances generally do not dissolve in water.
  • Valence electrons are the outer-shell electrons of an atom.
  • Van der Waals forces are weak intermolecular forces that arise from temporary fluctuations in electron distribution.

Physics

  • The specific gravity of a substance is the ratio of its density to the density of water.
  • Surface tension is the cohesive force that exists among molecules at the surface of a liquid.
  • Ohm's Law states that the current flowing through a resistor is directly proportional to the voltage across the resistor.

Other

  • A regular polyhedron having 12 regular pentagons is called a dodecahedron.
  • Work-in-process is classified as an asset.
  • IPC (Indirect Product Cost) spending variance is the difference between actual IPC and IPC volume adjusted budget.
  • Dividend yield is the index that gives the rate earned per share based on the current price per share.
  • A complex plane is a diagram used in complex algebra to represent a complex number.
