Determine which quadrant and angle lies in radians in terms of pie - math help free

👉 Learn how to determine the quadrant of an angle given in radians. Recall that 1 radian is the distance on the circumference of the circle that is equivalent to the radius of the circle. Also, recall that the circumference of a circle is equivalent to 2pi radians.

To determine the quadrant of the angle in radians written in terms of pi, we divide the top half and the bottom half of the circumference of the circle into the number of parts corresponding to the denominator of the radian angle. Then we count from the positive x-axis in an anti-clockwise direction for positive angles and in the clockwise direction for negative angles the number of parts corresponding to the coefficient of pi in the numerator.

The quadrant where the number of parts corresponds to the coefficient of the pi in the numerator of radian angle is the required quadrant.

Incredible video. I am taking pre calculus independently and I was stuck on this concept. You broke it down perfectly. thank you so much

[brianmclogan]

Oh I have plenty more to make!, happy to help

[brianmclogan]

good question, it's all about estimation. Between the third and fourth quadrant is 3pi/2 and 2pi. Convert those to decimals and if 5.63 is between those two numbers then it's within the fourth quadrant.

[bRKEllEZAYANI]

thank you! you're literally the only person who has explained this to me clearly. trig final tomorrow and i am just now learning this smh.

[brianmclogan]

I really enjoy what I do, so responding to everyone is a treat!

[IanusKhan]

You know what is the great part? That you don't use too much math vocabulary and you keep it my honors calc teacher does.

[comfyaura]

It's 2022, and this video explained it so well. I'm stuck on trig in my precal college class. The last time I did precal I was 15 and now I'm 20.

[ladymiss]

Great Explanation! I'm 36years old and I've never understood this simple concept until NOW🥰

[parichawlaa]

I was so confused cause the solution just straight up named the quadrant. Thank you so much for this explanation, cleared it all up for me!

Thanks for the technique for sketching the radians! My teacher didn't teacher this method, but it is easier to understand for me.

[brianmclogan]

that is a lot of practice behind my belt. Keep up the hard work.

[EllaBellaMella]

SOOO helpful Thank you. They way you changed pi and 2pi according to the problem each time is what has saved me, Thank you.

[hellandheaven]

Hlo, sir I'm sarvesh from india. we are not well in English but in maths i solved IIT question (you known Ramanujan, Arayabhatta ) all are from same State.

This video was fantastic. You've helped educate me for the past couple of months, thank you so much.

[AmberRoseMiles]

I understand this a lot better now, thank you. although, for the 22pie/10, would the reference angle be 2pie/10 or 22pie/10?

[lilyjaronczyk]

So much easier to understand when you break the fractions that way!! Thank you!

[christiangarcia]

Miranda needs to stop interrupting your gorgeous lessons

[abbiesapp]

I'm taking pre calc online this year, and despite having an amazing teacher myself (she was a savior when my 9th grade algebra 2 teacher taught me nothing) she hasn't put out many resources for online kids, and we dont start video classes until next week

[brianmclogan]

nice work, congratulations to you, keep up the hard work!

[NYCGemini]

thank you man. this video helped me alot lol its alot better than just reading my precalculus book
