Step 1: Choose a series of x-values that are very close to the stated x-value, coming from the left of the number line. For this example, I’ll use the sequence values for x from above: 2.9, 2.99, 2.999, 2.9999, 2.99999 Step 2: Enter your x-values into the given function. The...
My teacher wants us to make a matrix for this circuit to use it on (https://www.desmos.com/matrix), so we can get the currents. However, I don't know how to make the matrix and don't understand how to loops work. Follow • 1 Add comment 1 Expert Answer Best Newest...
A great and free example of one is Desmos.Graphing Calculators Graphing calculators can be used to complete arithmetic, just like regular calculators, but they can also be used for more advanced functions such as evaluating algebraic expressions and functions at a given value, and graphing ...
Note: If the bounds of integration aren’t integers (the second integral here has e, Euler’s number), you may want to use a graphing calculator (I used the one at Desmos.com to draw this graph) so you can more easily sketch the shape. Step 3: Find the shaded area that meets the...
(If you ever wondered why “two negatives equal a positive” in algebra, this last example, 4 – -2 helps to explain why!). When do we use absolute value in statistics? In general. we use absolute values when we don’t care about the sign of the number — we just care about it’...
Using transformations to graph functionsSometimes we can use the concept of transformations to graph complicated functions when we know how to graph the simpler ones.For example, if you know the graph of f(x), the graph of f(x) + c will be the same function, just shifted up by c ...
Bernstein polynomials are used instatistics for smoothingand as a basis for Bezier elements used inisogeometric analysis[4]. They form the mathematical foundation for computer-aided geometric design (CAGD); Adobe’s Illustrator and Flash, as well as font imaging systems like Postscript; all use Be...
When you tackle a normal distribution problem in a statistics class, you’re trying to find the area under the curve. The total area is 100% (as a decimal, that’s 1). Normal distribution problems come in six basic types. How do you know that a word problem involves normal ...
Step 3:Evaluate bnto see if it decreasing. One way to do this is to graph the function (I usedDesmos.com): Clearly, the function (and therefore the sequence) is decreasing and thelimitas n→∞ is 0. Therefore, this series converges. ...
