# Math Flashcards

Some mathematicians used to say that math is in everything. The thing is, the more you learn about the world, the more you realize how true that is. All these things that seem to come out of nowhere without any particular meaning or order actually fit perfectly with anything around them. To some, is almost as if math is a common denominator to anything in existence.

But let’s put aside all these things, for now, and look at what we’ve got in the Math flashcards. By definition, the first two numbers in the Fibonacci sequence are which ones? In calculus, L'Hôpital's rule uses derivatives to help evaluate limits involving what? What was the name of the mathematician that is said to have discovered the possibility of non-Euclidean geometries but never published it? Check out all of our other Math flashcards.

• Side A: Ellipsoid
Side B: x^2/a^2 + y^2/b^2 + z^2/c^2 = 1All Traces are ellipsesIf a=b=c, sphere

• Side A: Cone
Side B: z^2/c^2 = x^2/a^2 + y^2/b^2Horizontal Traces are ellipsesVertical traces in planes x=k and y=k are hyperbolas if k is not 0, a pair of lines if k=0

• Side A: Elliptic Paraboloid
Side B: z/c= x^2/a^2 + y^2/b^2Horizontal Traces are ellipsesvertical traces are parabolasVariable raised to the first power indicates axis of paraboloid

• Side A: What are the two Breakeven Point equations:
Side B: BEP= FC/ (REV – VC)             Or BEP= FC/ (R-V) FC= fixed costs REV= V= VC= Variable costs

• Side A: What are the two capacity formulas?
Side B: Efficiency= (Actual output/ effective capacity) X 100Utilization= (Actual Output/ Design Capacity) X 100

• Side A: What is the formula to find the CYCLE TIME?
Side B: Cycle Time= Operating Time per day / Desired output rate
