在以前的Windows版本中，默认的计算器应用程序非常标准，坦率地说毫无用处。不过，微软(Microsoft)决定大幅升级Windows 11中的计算器应用程序。
升级带来了新功能，例如科学计算器、程序员功能等。其中之一是图形计算器，它可以为市场上的标准图形计算器（如德州仪器(Texas Instruments)）提供竞争优势。
在本文中，我们将介绍如何在Windows 11中访问图形计算器，如何输入和绘制函数，以及如何使用计算器求解图形中的值。
如何在Windows 11中打开(Windows 11)图形计算器(Graphing Calculator)
要打开图形计算器，请单击开始(Start)菜单并在搜索字段中输入“计算器”。然后，选择计算器(Calculator)应用程序。
这将打开标准计算器应用程序。除非您想选择左上角的菜单，否则您永远不会知道这不仅仅是旧的 Windows 10 计算器应用程序(old Windows 10 calculator app)。
当您选择菜单时，您将看到所有可用于高级计算器功能(advanced calculator features)的选项。
要访问图形计算器，请从菜单中选择图形。图形计算器将在同一个小窗口中打开。因此，除非您使用右上角的小切换按钮将显示从计算器绘图模式切换到方程式模式，否则您只会看到图表。
使用图形计算器的更好方法是调整窗口大小，直到图形区域和公式编辑器并排出现在同一个窗口中。
现在您已准备好使用这款功能强大的 Windows 11 图形计算器。
如何在Windows 11中使用(Windows 11)图形计算器(Graphing Calculator)
为了演示图形计算器的工作原理，我们将从一个简单的二次方程开始：y = x² + 2。
在输入(Enter)表达式字段中输入此公式，然后选择蓝色的Enter按钮。您将看到图形出现在 x 轴和 y 轴上方的左侧窗格中。
现在，图形计算器的全部意义在于，当给定不同的 x 值时，您可以求解 y 的值。然后，您可以使用光标跟踪图形以查看这些值，例如 y 截距（当 x = 0 时）。
您还可以使用图形计算器来操作表达式中的变量，并查看这些变化如何影响图形。当学生学习代数以及函数的不同元素如何影响输出结果时，这些很重要。
一个很好的例子是线性函数 y = mx + b。这是学生学习了解图表中直线的斜率和位置如何与每个变量相关的第一个函数。
将该函数键入为另一个表达式，然后按蓝色的Enter按钮将其绘制成图表。
您可能会注意到您的图表不在显示中居中，或者您看不清楚。您可以使用图表右下角的 + 和 – 按钮来放大和缩小。您也可以在图形区域的任意位置单击鼠标左键并拖动鼠标，以向任意方向滑动显示。
如果您选择图表右上角的图表选项图标，您还可以选择调整 x 和 y 的最小值和最大值。(Graph)这是调整图表显示区域的另一种方法。
您还可以在弧度(Radians)、度数(Degrees)和梯度(Gradians)之间调整单位。
图形居中后，尝试操纵变量以查看它如何影响输出。上面的线性函数(linear function)有两个变量，m 和 b。如果您使用表达式右侧的滚动条向下滚动，您将看到显示这些表达式变量的部分。图形计算器已经对这些变量的图表价值做出了假设。
尝试调整线性函数中的b变量；你会注意到这条线在 y 轴上移动了你输入的值。
尝试调整 m 变量。您会看到，当您使用线性方程执行此操作时，它会增加或减少直线的斜率。
您可以通过选择表达式右侧的分析(Analyze)函数图标来
查看有关您输入的每个表达式的更多详细信息。
当您选择此选项时，图形计算器将分析您的表达式并提供重要信息，例如 x 截距、y 截距等。
其他Windows 11 图形计算器功能(Graphing Calculator Features)
要删除您在计算器中输入的任何表达式，只需选择等式右侧的删除(Remove)等式图标。
这将从图形计算器显示中删除方程和图形。
使用函数(Function)下拉列表来合并绝对值等内容。
使用Trigonometry下拉菜单在表达式中包含 sin、cosine、tangent 和其他三角函数。
您可以使用不等式下拉列表来绘制包含不等式而不是等号的表达式。这将在您的图表上显示为图表区域下方或上方的阴影，其中存在不等式。
创建图表后，您可以选择图形区域右上角的共享图标，将该图表的屏幕截图发送给其他人。
此处列出的选项取决于您的Windows系统上安装的内容。典型的选项将包括电子邮件。但是，如果您有其他应用程序，例如OneNote、Facebook或其他通信应用程序，您也会在此处看到这些应用程序。

How to Use the Graphing Calculator in Windows 11
In previous versions of Windows, the default calculator app was pretty standard and frankly useless. However, Microsoft decided to upgrade the calculator app in Windows 11 significantly.
With that upgrade came new features such as a scientific calculator, programmer functions, and more. One of those is a graphing calculator that can give standard graphing calculators on the market, like Texas Instruments, a run for their money.
In this article, we’ll cover how to access the graphic calculator in Windows 11, how to enter and graph out functions, and how to use the calculator to solve for values along the graph.
How to Open the Graphing Calculator in Windows 11
To open the graphing calculator, click the Start menu and type “calculator” in the search field. Then, select the Calculator app.
This will open the standard calculator app. And unless you think to select the menu at the upper left, you’d never know that this isn’t just the same old Windows 10 calculator app.
When you select the menu, you’ll see all the options available for advanced calculator features.
To access the graphing calculator, select Graphing from the menu. The graphing calculator will open in the same small window. So, you’ll only see the graph unless you switch the display from calculator graphing mode to equation mode using the small toggle button at the upper right.
A better way to use the graphing calculator is to resize the window until both the graphing area and the equation editor appear side by side in the same window.
Now you’re ready to use this powerful Windows 11 graphing calculator.
How to Use the Graphing Calculator in Windows 11
To demonstrate how the graphing calculator works, we’ll start with a simple quadratic equation: y = x² + 2.
Type this formula into the Enter an expression field, and select the blue Enter button. You will see the graph appear in the left pane over the x- and y-axis.
Now, the whole point of a graphing calculator is so that you can solve for values of y when given different values for x. Then, you can trace the graph with your cursor to see these values, such as the y-intercept (when x = 0).
You can also use the graphing calculator to manipulate variables in your expressions and see how those changes affect the graph. These are important when students are learning algebra and how different elements of a function affect the output results.
A good example is the linear function y = mx + b. This is one of the first functions students learn to understand how the slope and position of a line in a chart are related to each variable.
Type that function as another expression and press the blue Enter button to chart it.
You may notice that your graph isn’t centered in the display, or you can’t see it well. You can use the + and – buttons at the lower right corner of the chart to zoom in and out. You can also left-click and drag the mouse anywhere in the graph area to slide the display in any direction.
If you select the Graph options icon at the upper right corner of the chart, you’ll also have the option to adjust the min and max values for x and y. This is another way to adjust the display area of the chart.
You can also adjust units between Radians, Degrees, and Gradians.
Once your graph is centered, try manipulating variables to see how it affects the output. The linear function above has two variables, m, and b. If you scroll down using the scroll bar to the right of your expressions, you’ll see a section showing these expression variables. The graphing calculator has made assumptions about what value these variables are to chart it.
Try adjusting the b variable in the linear function; you’ll notice that the line shifts up the y-axis by the value you’ve entered.
Try adjusting the m variable as well. You’ll see that when you do this with a linear equation, it will increase or decrease the slope of the line.
You can see more details about each expression you’ve entered by selecting the Analyze function icon to the right of the expression.
When you select this, the graphing calculator will analyze your expression and provide important information like the x-intercept, the y-intercept, and more.
Other Windows 11 Graphing Calculator Features
To remove any expressions you’ve entered into the calculator, just select the Remove equation icon to the right of your equation.
This will remove the equation and the graph from the graphing calculator display.
Use the Function dropdown to incorporate things like absolute value.
Use the Trigonometry dropdown to include sin, cosine, tangent, and other trigonometric functions in your expression.
You can use the Inequalities dropdown to chart expressions that include inequality instead of an equal sign. This will be represented on your graph as shading below or above the area of your chart where that inequality is true.
Once you’ve created your graph (or graphs), you can select the share icon in the graphing area’s upper right corner to send a screenshot of that chart to other people.
The options listed here will depend on what’s installed on your Windows system. The typical option will include email. But if you have other apps like OneNote, Facebook, or other communication apps, you’ll also see those listed here.
