Where ever input thresholds (or boundaries) require significant changes in output modeling, you will find piece-wise functions. In your day to day life, a piece wise function might be found at the local car wash: $5 for a compact, $7.50 for a midsize sedan, $10 for an SUV, $20 for a Hummer. Or perhaps your local video store: rent a game, $5/per ... PiecewiseExpand[expr] expands nested piecewise functions in expr to give a single piecewise function. PiecewiseExpand[expr, assum] expands piecewise functions using assumptions. PiecewiseExpand[expr, assum, dom] does the expansion over the domain dom.

I am relatively new to Mathematica, and am having difficulty doing something that is conceptually very simple.

A piecewise function is a function built from pieces of different functions over different intervals. For example, we can make a piecewise function f(x) where f(x) = -9 when -9 x …

As I mentioned in a comment, NIntegrate does solve the condition 1.1 x^0.045 < 1 for the singularity at x == b2bar and this causes a problem with the integration, which is itself an issue. But that issue can be avoided by reducing the condition to something NIntegrate can handle. If we throw in the domain restriction 0 <= x <= 1 && 0 <= y <= 1 …

The interpolating function returned by Interpolation [data] is set up so as to agree with data at every point explicitly specified in data. The function values f i can be real or complex numbers, or arbitrary symbolic expressions. The f i can be lists or arrays of any dimension. The function arguments x i, y i, etc. must be real numbers.Here the objective function tends to the maximum value when y tends to infinity: Maximize can solve linear programming problems: LinearProgramming can be used to solve the same problem given in matrix notation:Give Top. Introduction for Programmers. UnitStep [x] represents the unit step function, equal to 0 for x < 0 and 1 for x >= 0. UnitStep [x1, x2, ...] represents the multidimensional unit step function which is 1 only if none of the xi are negative.You can use Piecewise to define your piecewise functions. For example your second example could be defined as follows: f[x_] := Piecewise[{{1/(2 x^2), Abs[x] > 1}, {0, True}}] Integration: Integrate[f[x], {x, -3, 7}] yields 16/21 Mathematical functions that evaluate depending on the values of their arguments include Boole and Piecewise. Condition is a pattern that matches only if the evaluation of a test results in True. TrueQ is a specific case of If that yields True if an expression is explicitly True, and False otherwise.

So, when you used inside this last set of functions what occurs is something like this. Piecewise[{conditions in …1 Answer. Sorted by: 4. Use Evaluate for this purpose: f [x_] := Evaluate@Piecewise [envpart] Make sure that x has no value assigned. ClearAll [x] before will handle this. This operation is described in Evaluate documentation. 3rd/4th example in Applications section. Jul 7, 2015 · You seem unfamiliar with Mathematica syntax. gr[x_] := Piecewise[{{x, x > 1}, {0, x <= 0}}]; Plot[gr[x], {x, -5, 5}] Note too that your function is not defined for $0 < x \leq 1$. Is that really what you want? It is also good programming style to order the elements in a Piecewise from low to high (left-to-right on the number line), i.e., Application of Definite integrals of piecewise function. Below are some examples of piecewise functions that are very often seen in mathematics, Modulus Function, |x|. Modulus function are the functions that break at a point, and they are represented as, Greater Integer Function, [x] In definite integrals, if the value obtained is …

Find and classify the discontinuities of a piecewise function: The function is not defined at zero so it cannot be continuous there: The function tends to Infinity (on both sides), so this is an infinite discontinuity:
