Reference Angle for an Angle

Reference Angles: How to Find Them
In this video, we explore how to determine the reference angle for different angles, including 165°, 460°, -40°, and -283°. Reference angles are useful in trigonometry for simplifying problems and understanding the relationship between angles on the unit circle.

Learn the definition of a reference angle and why it's always positive
Find the reference angle for angles greater than 360° or less than 0°
Apply the concept to both positive and negative angles
Watch the video to see step-by-step explanations for finding reference angles in various scenarios. If you find it helpful, please like, share, and subscribe for more math content!

I was so confused about this for so long, this is so easy really. Thanks!

I was utterly confused by this until I looked up exactly what a reference angle is... somewhere between 0 and 90 degrees not more or less. I know this is a real basic concept but it would've been helpful to mention that! Beyond that, thanks for all you do!

OMG, you made it so easy to understand !!!

My jc trig teacher has a PhD in math for 20 years. He just breathes math. I am so thankful for your help!!!

U are awesome thanks I need so much help for my homework but I'm still not sure what to do with my homework and I was so excited to be on the same page with my

No. It always starts from the right side of the x axis. So, if it's a positive degree, It will move in counter-clockwise direction and if it's a negative degree, It will move in a clockwise direction.

Thank you for the clear explanation. I'm very glad you did 4 questions to fully show every scenario. I love you

You are my hero, please be my pre-calc teacher. Thank you so much!

[bobboestiasy]

This is a really good explanation for this! Keep up the good work!!

[wackyweirdochic]

I read my textbook and it didn't even explain how to find reference points. It just threw in example problems that confused me even further. You made this so easy, so I'll be prepared for my precalculus exam! Thanks.

Hey dude, at 3:14 you find the absolute value of the angle -40 degrees. Why can't it be negative? Why only positive? It seems like it is fine if we leave all the trig functions negative in their certain quadrants. For example: In quadrant II cos, tan are negative, why not find the absolute value of those and represent them as positive values too.

He literally made one full lesson fit in 5:44 mins
thanks

How many degrees have you "went"? Hey, no one is perfect. Thank you for these videos Patrick.

Thanks, helped so much with my homework and I've hit a quiz tomorrow so this really helped me to review!

Patrick JMT, Thank you much for doing these videos. The help so much.

[lavenderbrown]

Thank you so much sir, I wish my trigo teacher explained it like this. Thanks a lot!

[erlajade]

Thank you so much. Please continue helping students like me.💜

Dude! thanks a lot for the help!!!! i'm learning this for my exam and thanks to you, i understand this lesson VERY WELL. =)

[justenereyes]

OMG thank you so much. I am studying for my test tomorrow and I really can't understand this lesson because of my confusing teacher. But when I watched your video, I understood it already. Thank you so much ❤️

Thank you, I'm working on pre-calc work book to brush on pre calc stuff for my intro to calc stuff I usually like to refer to Khan academy but they didn't have a video on this and let me tell your as amazing as Sal khan
