Understanding coterminal angles in trigonometry

👉 Learn the basics of co-terminal angles. An angle is a figure formed by two rays that have a common endpoint. The two rays are called the sides of the angle while the common endpoint is called the vertex of the angle. We measure angles starting from the positive x-axis, i.e. the initial side of an angle measure is usually the positive x-axis. The angle measured in the anti-clockwise direction is called a positive angle while a negative angle is measured in the clockwise direction.
Two or more angles are said to be co-terminal when they have the same initial and terminal sides. Coterminal angles are found by adding/subtracting 360 degrees (for degree angle measure) or 2pi (for radian angle measure) to/from the given angle.

Im not sure if this is sad or impressive but your videos have gotten me through math since my sophomore year in highschool. Thank you for making math understandable

[@taylorpack2839]

Dude, you’re such a big help, thank you

[@raquelsancon5868]

I've been struggling with my sched in our online class, I haven't attended 2 sessions in our precal class, but I'm thankful that you're existing sir. Our precal advicer is also excellent in teaching but she's kinda busy and I don't want her to divide her time just to answer my clarification.(Especially if I can study the lesson on my own using yt tutorials.) She's amazing like you sir. Thank you for all the Mathematics teacher that are doing their best to help their students!!!❤️

[@DanielleRounds]

my math professor is no help whatsoever and you are a lifesaver! Thank you so much for this

[@dariusfrailey5370]

Sadly this year i have a pretty bad math teach and can say that i am very thankful for your lessons because you have taught me everything so far this year. Thankyou🙏🏾

[@thewyk]

I love when you pointed out subtracting by 360 twice. I had to find a negative coterminal angle of 660, so 660 - 720 = -60
Thanks!

[@brianmclogan]

you are very welcome! happy to be able to help
