Degrees Symbol on Iphone Calculator

Reviewed by Calculator Editorial Team

The degrees symbol (°) is an essential part of trigonometric calculations on the iPhone calculator. This guide explains how to locate and use this symbol effectively.

How to Find the Degrees Symbol

On the iPhone calculator, the degrees symbol is located in the trigonometric functions section. Here's how to access it:

  1. Open the Calculator app on your iPhone.
  2. Tap the "2nd" button at the top of the calculator to switch to the second function set.
  3. Look for the trigonometric functions (sin, cos, tan) in the second row.
  4. The degrees symbol will appear next to these functions, indicating that the calculator is in degree mode.

Note: The degrees symbol only appears when the calculator is in degree mode. If you don't see it, make sure you've tapped the "2nd" button first.

Switching Between Degrees and Radians

The iPhone calculator can work with both degrees and radians. Here's how to switch between them:

  1. Tap the "2nd" button to enter the second function set.
  2. Tap the "Rad" button to switch to radian mode.
  3. Tap the "Deg" button to switch back to degree mode.

Formula: To convert between degrees and radians:

Degrees to Radians: radians = degrees × (π/180)

Radians to Degrees: degrees = radians × (180/π)

Example: To calculate sin(30°), you would first ensure the calculator is in degree mode, then press "sin" followed by "30" and "=". The result should be 0.5.

Using the Degrees Symbol

Once you've located the degrees symbol, you can use it in your calculations:

  1. Make sure the calculator is in degree mode (you should see the degrees symbol).
  2. Enter your trigonometric function (sin, cos, or tan).
  3. Enter your angle value.
  4. Press "=" to get the result.

Example: To calculate cos(60°):

  1. Ensure degree mode is active (degrees symbol visible).
  2. Press "cos".
  3. Press "6".
  4. Press "0".
  5. Press "=". The result should be 0.5.

Common Errors

When working with the degrees symbol, you might encounter these common issues:

  • Forgetting to switch to degree mode: If you don't see the degrees symbol, you're in radian mode. Tap "2nd" then "Deg" to switch.
  • Entering angles incorrectly: Remember that trigonometric functions expect angles in degrees when in degree mode.
  • Confusing degrees and radians: Keep track of which mode you're in, as results will differ significantly between degrees and radians.

FAQ

Where is the degrees symbol on the iPhone calculator?
The degrees symbol appears next to trigonometric functions (sin, cos, tan) when you're in degree mode. Tap the "2nd" button first to see it.
How do I switch between degrees and radians on the iPhone calculator?
Tap the "2nd" button, then tap "Rad" to switch to radians or "Deg" to switch back to degrees.
What happens if I don't see the degrees symbol?
You're in radian mode. Tap "2nd" then "Deg" to switch to degree mode and see the degrees symbol.
Can I use the degrees symbol for non-trigonometric calculations?
The degrees symbol is primarily for trigonometric functions. For other calculations, you can simply enter the number without the symbol.
Why does my calculator show different results for the same angle in degrees and radians?
Trigonometric functions produce different results in degrees and radians because they use different scales. Make sure you're using the correct mode for your calculation.
