Plot 100x (1 –- x) and the partial sums SN (x) for N = 1, 3, and 5 one- by-one on the same graph to get a feeling for how well the partial sums of the series approximate the initial temperature profile. %3D Now, find N so that SN (x) approximates 100x (1 – x) to within 10-6. (Remember 0 < x < 1.) Hint. Express the error |u (x, 0) – Sn (x)| as an infinite series and make an area comparison to estimate the size of the error series.
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
