Constructing algebraic objects

How do I...

enter a piecewise expression or function

 • Example 1.1: Use the piecewise template from the Expression palette
 •
 •

enter an algebraic equation

 • See Example 1.2.

create a sequence

 • Context Panel: Sequence
 •
 •

construct a loop

 • See Example 1.3.

write the exponential function ${ⅇ}^{x}$

 • Example 1.4: Use the exponential template from the Expression palette or use Command Completion in Math mode

enter ${\mathrm{log}}_{a}\left(x\right)$

 • In Math mode, the expression can be entered normally with the $a$ entered as a subscript.  To enter the subscript level, hold down [Ctrl] and press underscore [_]; after typing the subscript, press the right arrow key to leave the subscript.  Finish the expression by entering $\left(x\right)$
 • Example 1.5: Use the log template from the Expression palette
 • In Maple Input mode, log[a](x) can be used to represent ${\mathrm{log}}_{a}x$

convert an expression to a function

 • Context Panel: See Example 1.6
 •

write a procedure

Algebraic manipulations

How do I...

obtain the equation of a line

 •

obtain the coordinates of the midpoint of a line segment

 •

obtain the slope of a line segment

 • Task: Line Segment - Slope

compute the distance between two points

 •

complete the square

 • Context Panel: Complete Square

square both sides of an equation

 •
 • Context Panel: Manipulate Equation

substitute into an expression

 • Context Panel: Evaluate at a Point
 • Context Panel: Constructions → Evaluate At → [variable name] (yields unevaluated evaluation)
 • Use the template $\genfrac{}{}{0}{}{{f}\left({x}\right)}{\phantom{x=a}}|\genfrac{}{}{0}{}{\phantom{\mathrm{f\left(x\right)}}}{{x}={a}}$from the Expression palette; replace with the expression on which to perform the substitution, and overwrite ${x}={a}$ with either the variable name equated to a value or a list of such equations
 •
 • Use the command eval to substitute a variable or value into an expression

substitute into an equation

 • Use any of the devices for substitution into an expression, except that the Context Panel for an equation does not provide the Constructions option

obtain the solution to RootOf

 • Context Panel: All Values
 • Context Panel: Conversions → To Radical
 • Use the allvalues command.

force an equation to be an identity

 •
 • Use the command solve(identity(eqn, x), vars); the expression (or equation) eqn is considered an identity in terms of the variable x, and solve attempts to find a solution in terms of vars that satisfies eqn for any value of x.

determine the inverse of a function

 • Function Inverse Tutor:

interpolate data

 • Context Panel: Curve Fitting → any of B-Spline, Interactive Curve Fitting, Least Squares, Polynomial Interpolation, Rational, Spline, Thiele
 • Curve Fitting Assistant: This assistant also allows you to import data into Maple from an external file to produce plots of various interpolating functions (Example 2.1)
 •
 •
 •
 •
 •
 •
 •

obtain a partial fraction decomposition of a rational function

 • Context Panel: Conversions → Partial Fractions → [variable name]
 •
 •
 • The command convert(f, parfrac, x) converts a function, f with main variable, x into partial fractions.

obtain real values of ${x}^{1/3}$

 • Use the surd command.
