Section 2: Techniques for Making a Curve in Desmos

1. Using the Function Input

Desmos is primarily a function graphing calculator, so using the function input is the most common and efficient way to make a curve. To create a curve, you need to enter a mathematical expression into the function input field. Desmos highly recognizes basic mathematical operators like ‘+, -, /, and *’ as well as trigonometric and exponential functions like sin(), cos(), tan(), log(), and so on. You can also use constants like e and pi.

2. Using Sliders to Control the Curve

Want to control and change the points of your curve easily? Using the slider feature in Desmos comes in handy. You can fix some of the values and allow others to change, creating a lively interactive experience. To use this feature, simply insert a slider by typing “a=” (or any variable you like) and your desired number or range in the function input field. After that, you can add ‘a’ into the function equation so that it changes as the slider moves.

3. Using Table Input to Plot Points

If you prefer plotting points manually rather than using a function, Desmos has got you covered. With the table input feature, you can add points by either clicking on the coordinate plane or typing them manually. After that, you can insert a regression model such as a linear or quadratic fit through the data points creating a beautiful curve graph.

4. Using Animations to Bring Your Curve to Life

Animations in Desmos are pretty awesome. You can create animations with input sliders or by using time-based animations. Once you set your desired animation parameters, Desmos automatically animates the curve. For example, you can make rotating flowers or a curve that simulates a heartbeat. Desmos has infinite possibilities.

5. Using Implicit Functions to Achieve Complex Curves

Creating a complicated mathematical curve in Desmos might be quite hard using simple functions. Luckily, Desmos supports implicit functions that can help you achieve more complex curves. Implicit functions are equations or expressions that aren’t in a form that Desmos can handle straightforwardly. To use this feature, insert an ‘=’ sign into the function input field to specify the relation between x and y.

6. Using Polar Equations for Circular Curves

Polar equations are commonly used by mathematicians and physics experts who need to work with circular and spiraling curves. Desmos has made it easy for users to input polar equations in the function input field. To create a polar curve, use the “r(θ)=” function format where ‘θ’ represents the angle, and ‘r’ represents the radius.

7. Using Function Families to Create Multiple Curves

With the function family feature, you can produce multiple curves with various values of parameters. This is a quick way to experiment with different curves and functions. Insert a function with a variable parameter like “f(a,x)=” into the input field and set the range of ‘a.’ Desmos will generate multiple graphs, one for each value of ‘a.’ This feature is perfect for comparing graphs.

8. Using Lists to Define a Curve

Another way to define complex curves is by using lists in Desmos. Lists are sequences of numbers or values that can be used in function equations. They are useful for creating complex curves like fractals. To use the list feature, input a list of values separated by commas into the function input field like “f(x1,x2,…,xn)” then insert your desired mathematical expression involving the list values.

9. Using Parametric Equations for Animated Curves

If you want to create animated curves with different properties like speed, direction, or proportionality, then the parametric equations feature might be perfect for you. This feature operates with two equations called ‘x(t)’ and ‘y(t)’ that represent the horizontal and vertical components of the curve vector, respectively, as a function of ‘t.’

10. Using Advanced Topics to Polish Your Curve

There are some advanced topics in Desmos that can help you polish your curve, making it look professional and optimized. These topics include the use of colors, controlling the thickness of curves, adding labels and annotations, using text inputs, and so on. You can learn more about these topics from the tutorials on Desmos’s official website.
