Quadratic equationsare mathematical functions where one of the x variables is squared, or taken to the second power like this: **x2**. When these functions are graphed, they create a parabola which looks like a curved "U" shape on the graph. This is why a quadratic equation is sometimes...
We show that any first-order ordinary differential equation with a known Lie point symmetry group can be discretized into a difference scheme with the same... MA Rodríguez,P Winternitz - 《Physics》 被引量: 57发表: 2004年 Industry Reallocations in a Globalizing Economy We distill the main ins...
Refer to a table of ions to find the charges of the positive and negative ions in the compound. Chemical formulas, by convention, list the positive ion first. In the compound calcium bromide, or CaBr2, for example, the calcium represents the positive ion and exhibits a charge of +2. Br...
If a triangle contains two unknown sides, then more complex trigonometric formulas and algebraic proofs will have to be applied in order to find them. This same mathematical theorem can also be applied to physics problems like triangular force vectors. What Is a Right Triangle? A right angled ...

Function: a predefined formula built into the app used to manipulate data and calculate cell, row, column, or range values. For example, you can use the function =SUM to calculate the total value of a given cell range. Formula: any equation designed by an Excel user to perform calculatio...
You'd be hard-pressed to find a trader who has never heard of John Bollinger and his namesake bands. Most charting programs includeBollinger Bands. Although these bands are some of the most usefultechnical indicatorsif applied properly, they are also among the least understood. One good way to...
Use the "Graph" function on your graphing calculator. The "Y=" button opens the graphing function on most calculators. To find how to graph using your calculator, consult the owner's manual. Step 2 Enter the left side of the equation into the first "Y=" line. For example, if you hav...
To really help this concept stick, take a look at the following calculations that find the elasticity modulus of different materials: 1. Steel In this example, we’ll look at a steel rod and find Young’s modulus for it. Consider the equation if the following factors are true: The rod ...
