Using the period as an aide evaluate the function for the given trig function

👉 Learn how to evaluate trigonometric functions of a given angle. Given an angle greater than 2pi in radians, to evaluate the trigonometric functions of the given angle, we first determine the smallest positive coterminal angle of the given angle. This we can do by subtracting 2pi or a multiple of 2pi from the given angle.

Coterminal angles are angles with the same terminal side. After obtaining the coterminal angle, we plot the angle on the x-y-coordinate plane and with the help of the Pythagoras theorem or the special angles, we can evaluate the trigonometric functions of the given angle.

Thank you so much! My teacher makes us learn the lesson at home and then do the assignment at school. You do a much better job explaining than the Precalculus textbook.

Sit down, we still have five more minutes of learning the language of the universe.

Thank you so much haha my test is tomorrow and my book wasn't making any sense and now I can wrap my head around things again!

[wolvesruleAJ]

Your explanations have saved me multiple times when I need help understanding something. Thank you!! :)

[ryanb.]

Thanks man my precalc teacher fists us by not teaching us half the lesson big shoutout

[brittanybeland]

Thank You for your help!!! You are an awesome teacher :)

Good vids, Watched a few. Been great in math up to the point of adding the unit circle and Trig. values. This is a great help, as trying to understand the book is just frustrating. Keep it up!

[talaalnaili]

thanks a lot for your effort, I have a question though, can we apply this (-2pi +t) to other trig. functions?? such as tan and cos???

With class online now and my teachers being so lazy I just relay on these videos to teach me everything for the year

[fiyin]

found your videos really helpful appreciate it

Plaese never call your teacher lazy, they do their level best, make sure you do the same
Math implies pencil and paper, memorising an pracrice.
