-2,77556E-17. This is just a simple example, but when it comes to larger Excel models it can be quite annoying. Especially if you want to compare the result – let’s say you want to check the result with an IF-formula if it equals 0. So what is the reason for these obviously ...
Step 4: Use algebra to manipulate the δ from Step 1. This time, your goal is to go from 0 < |x – 3|< δ): to |(2x + 4) – 10| < ε 0 < |x – 3|< δ = 0 < |x – 3|< ε/ 2 = (using the value for delta you derived in Step 2) 0 < 2|x – 3|< ε...
Binary logic refers to values having one of two states, TRUE or FALSE. This allows Boolean algebra in Excel using logical operators. What is a logical expression? A logical expression is a statement that evaluates to TRUE or FALSE. For example: ...
In algebra, some problems can be solved by using a process of elimination. Work through this process with increasingly complex sample problems by identifying the question, determining the known and unknown information, and applying elimination. ...
Certain word problems can be translated into an algebraic equation and solved in a single step. Learn the definition of a one-step algebra equation, and understand how to translate the practice word problem into an equation and solve in it one step. One-Step Algebra Equations One-step algebr...
But what if, instead of, say, a simple exponential function such as y = x3, you instead have to solve an equation like y = 3x. Here, x, the dependent variable, appears as an exponent. Is there a way to pull that variable down from its perch to more easily deal with it mathematica...
Identity matrices are fundamental to linear algebra and matrix operations. Excel has a dedicated function namedMUNIT functionthat creates an identity matrix of a given dimension. What is a determinant? The determinant is a special scalar value computed from a square matrix that provides crucial inform...
Reduce the following matrix to obtain a row equivalent matrix in row echelon form. \begin{bmatrix} 2 & 1 & 0 & 7\1 & 1 & -1 & 2\3 & 2 & 0 & 12\6 & 4 & -1 & 25 \end{bmatrix} Solve using row echelon form. 6x - 3y + 4z = 7 x - 3y - 4z = 8 3x + 4y +...
