# How to call equation number in Maple?

## How to call equation number in Maple?

Double-click on the equation label (in the far right side of the output). Use the shortcut keys Ctrl+L (Command+L, for Mac).

**How do you set digits in Maplestory?**

The Maple Digits environment variable controls the number of digits that Maple uses when calculating with software floating-point numbers.

- The default value of Digits is 10.
- The value of Digits is changed by using the assignment operator. For example, Digits:= 20;

### Can Maple solve equations?

The explicit solutions to high-degree polynomials can be very large, so Maple may return a solution using RootOf expressions as placeholders. Maple may also use RootOf expressions as placeholders when it cannot find an explicit form for the solution of a non-algebraic equation in one variable.

**What is Fsolve in Maple?**

The fsolve command numerically computes the zeroes of one or more equations, expressions or procedures. Output. • The solutions to a single equation are returned as an expression sequence.

## How do you get decimal answers in Maplestory?

Another way to get decimals is to use the maple word evalf to convert a result to decimal form. The Maple constant Digits is set to 10 by default. If you want to more or less digits of accuracy, use evalf with a second argument.

**How do you insert a formula in Maplestory?**

To represent an equation in Maple, use the = sign for equality. Example: Solve the equation for using the Context Panel option Solve>Solve for Variable>x. By default, Maple uses symbolic methods to find the exact solution. Example: Solve the equation for using Solve>Solve in the Context Panel.

### What does _Z mean in Maple?

The “RootOf” function means the root of the expression; in the expression, _Z is the variable. In this example, Maple found one solution to be 0, but the other “solution” is just the solution to 4*_Z + 4*sin(*_Z) +1=0.

**How do you find zeros in Maplestory?**

Use the Maple solve command to find roots of the expression. Use the Maple fsolve command to find roots of the expression….Exercises

- Plot the function over the interval .
- Find all roots using the fsolve command and label the output.
- Substitute each root back into the function to show that the answer is zero.

## What is Evalf in Maple?

The evalf command numerically evaluates expressions (or subexpressions) involving constants (for example, , , and ) and mathematical functions (for example, exp, ln, sin, arctan, cosh, GAMMA, and erf).

**How do you solve differential equations in Maple?**

Use the dsolve command to solve the ODE based on the initial conditions. Save the solution in the variable sol2. sol2 := rhs(dsolve({eq1,y(0)=3,D(y)(0)=-5},y(t))); sol2 := − 2 3 e(−t) sin(3t)+3e(−t) cos(3 t) We now have the exact solution of the equation.

### What are Subs Maple?

The subs command is used to make substitutions of one expression (variable, number…) for another within some other (presumably more complicated) Maple expression. In other. words, subs can be used for “plugging-in”.

**How do I solve an equation in Maple?**

If an equation cannot be solved analytically, then the only possibility is to solve it numerically. In Maple, the command to use is fsolve. The syntax for fsolve is very similar to that of solve. Sometimes when the solve command is used, the output looks like:

## How do I find the root of an expression in Maple?

Since not every expression can be factored and it is sometimes difficult to get the exact root based on the plot, the best method for finding roots is to use Maple’s solving capabilities. First, a plot of the function or expression is needed to determine how many roots there are.

**How do I use maple’s solve command?**

Once you know how many roots there are, you can use the Maple solve command. Here the “=” sign is used in the equation, not “:=” which is used for assignment. If you forget to type in an equation and only type in an expression without setting it equal to zero, Maple automatically sets the expression equal to zero.

### How do you use assumptions in Maple?

Assumptions on parameters can be used to get more specific solutions. Note also, the form of the output changes when variables are given in a list. The explicit solutions to high-degree polynomials can be very large, so Maple may return a solution using RootOf expressions as placeholders.
