How to Put the Degree Symbol in Desmos

Desmos is one of the most widely used graphing calculators on the web, and for good reason — it handles everything from simple linear equations to complex parametric curves with surprising elegance. But when you need to work with angles measured in degrees, one question comes up regularly: how do you actually insert the degree symbol (°) in Desmos?

The answer involves understanding how Desmos handles angle measurement internally, because the degree symbol in Desmos isn't just a cosmetic character — it changes how the calculator interprets your values.

What the Degree Symbol Actually Does in Desmos

Before getting into the how, it's worth understanding the why.

Desmos, like most mathematical software, defaults to radians for trigonometric functions. That means if you type sin(90), Desmos interprets that as the sine of 90 radians — not 90 degrees. The result won't be 1 as many users expect.

The degree symbol tells Desmos to treat the number before it as a degree value, converting it automatically. So sin(90°) correctly returns 1, because Desmos handles the radian conversion behind the scenes.

This distinction matters a lot for students working with geometry, physics problems, or any application where angles are described in degrees rather than radians.

How to Insert the Degree Symbol in Desmos 🎯

Method 1: Type It Directly from the Expression Bar

The most reliable method is using Desmos's built-in symbol support. When you're typing in the expression input field:

1. Type your number (e.g., 90)
2. Then type the degree symbol directly

On most systems, you can insert ° using:

• Windows: Hold Alt and type 0176 on the numeric keypad
• Mac: Press Option + Shift + 8
• Chromebook / Linux: Press Ctrl + Shift + U, then type 00B0, then press Enter
• Mobile (iOS/Android): Long-press the 0 key on the number keyboard — the ° symbol typically appears as an option

Once pasted or typed into the Desmos expression bar, Desmos recognizes ° and applies the degree conversion automatically.

Method 2: Copy and Paste

If keyboard shortcuts feel unreliable on your device, simply copy the symbol from elsewhere — a search result, a text document, or a Unicode character tool — and paste it directly into the Desmos input field. Desmos parses the pasted character correctly in most cases.

This is especially common workaround for users on tablets or devices where keyboard shortcuts behave inconsistently.

Method 3: Use Desmos's Built-In Keypad (Mobile and Tablet)

On the Desmos mobile app or when using Desmos in a mobile browser, the on-screen keypad includes a degree symbol under the functions or operators panel. Look for the f(x) or expanded keyboard options — the ° character is typically accessible without needing any external keyboard tricks.

The exact location of the symbol can vary slightly depending on whether you're using the app or browser version, and whether you're on iOS or Android.

Variables That Affect Your Experience

Not every user's path to the degree symbol is identical. Several factors shape which method works best:

Common Mistakes to Watch For

Typing the letter "o" instead of ° — These look similar in some fonts but behave very differently. Desmos will not recognize a lowercase "o" as a degree symbol.

Using the degree symbol without a number directly before it — The symbol needs to immediately follow a numeric value or expression to be interpreted correctly.

Expecting the symbol to appear in outputs — Desmos uses ° as an input modifier, not necessarily as a display character in all output contexts. The conversion still happens even if the rendered graph doesn't always show the symbol explicitly.

Degrees vs. Radians: When It Actually Matters 🔢

If you're graphing a function like y = sin(x) and want the x-axis to represent degrees, you have two options:

• Append ° to the x variable inside the function: y = sin(x°)
• Manually convert using the formula: y = sin(x · π/180)

Both approaches produce the same result. The ° method is more readable; the manual conversion is useful if you want to be explicit about the math or if you're working in an environment where the symbol input is inconsistent.

For users building interactive sliders with degree-based angles, attaching ° to the slider variable is generally the cleaner approach — it keeps the expression readable while letting Desmos manage the conversion.

When the Symbol Doesn't Seem to Work

If you've inserted the degree symbol and Desmos doesn't seem to be responding correctly, a few things are worth checking:

• Confirm the symbol is the actual Unicode degree character (U+00B0), not a similar-looking character like the masculine ordinal indicator (º, U+00BA)
• Check whether you're in the graphing calculator vs. the scientific calculator — behavior can differ slightly
• Refresh the page or restart the app — occasionally a cached state can cause input parsing issues

The specific behavior you encounter depends heavily on your browser, device, and which version of Desmos you're running — and those variables don't always behave the same way across every setup.
