# reference angle calculator mathway

Can you please send an image of the problem you are seeing in your book or homework? Our reference angle calculator is a handy tool for recalculating angles into their acute version. What are you trying to do with this input? How we find the reference angle depends on the. This is easy to do. When an angle is greater than 360°, that means it has rotated all the way around the coordinate plane and kept on going. c) 328˚, a) 165˚ is in quadrant II (90˚ < 165˚ < 180˚ ) This second angle is the reference angle. Is there a different problem you would like further assistance with? Mathway requires javascript and a modern browser. (angles from 180° to 270°), our reference angle is our given angle minus 180°. Copyright © 2005, 2020 - OnlineMathLearning.com. Download free on Google Play. When the terminal side is in the fourth quadrant (angles from 270° to 360°), our reference angle is 360° minus our given angle. This is useful for common angles like 45° and 60° that we will encounter over and over again.

(angles from 0° to 90°), our reference angle is the same as our given angle. We rotate counterclockwise, which starts by moving up.

Simplify the result. The calculator automatically applies the rules we’ll review below. ... Trigonometry. So, if our given angle is 332°, then its reference angle is 360° – 332° = 28°. Please submit your feedback or enquiries via our Feedback page. The sign may not be the same, but the value always will be. Now we would have to see that we’re in the third quadrant and apply that rule to find our reference angle (250° – 180° = 70°). Determine the reference angle that corresponds to each of the following angle. You may speak with a member of our customer support team by calling 1-800-876-1799. Mathway. Find the Reference Angle (3pi)/4. So, if our given angle is 33°, then its reference angle is also 33°. The reference angle is 360˚ – 328˚ = 32˚ While we cover a very wide range of problems, we are currently unable to assist with this specific problem. It’s always the smaller of the two angles, will always be less than or equal to 90°, and it will always be positive.

c) 328˚ is in quadrant III (270˚ < 328˚ < 360˚ )

Visit Mathway on the web. When an angle is negative, we move the other direction to find our terminal side. Here’s an animation that shows a reference angle for four different angles, each of which is in a different quadrant. This makes sense, since all the angles in the first quadrant are less than 90°. We just keep subtracting 360 from it until it’s below 360. Phone support is available Monday-Friday, 9:00AM-10:00PM ET.

Find the Reference Angle (49pi)/2. Visit Mathway on the web. We welcome your feedback, comments and questions about this site or page.

The reference angle is 249˚ – 180˚ = 69˚. Notice how the second ray is always on the x-axis. This article explains what a reference angle is, providing a reference angle definition. For instance, if our given angle is –110°, then we would add it to 360° to find our positive angle of 250° (–110° + 360° = 250°).

So, if our given angle is 110°, then its reference angle is 180° – 110° = 70°. This calculator can quickly find the reference angle, but in a pinch, remember that a quick sketch can help you remember the rules for calculating the reference angle in each quadrant. I will end the session - please reconnect if you still need assistance.
