Graphing the Tangent Function with a New Period

👉 Learn how to graph a tangent function. To graph a tangent function, we first determine the period (the distance/time for a complete oscillation), the phase shift (the horizontal shift from the parent function), the vertical shift (the vertical shift from the parent function) and the asymptotes (the two vertical lines which the graph does not touch). After we have obtained these features, we plot the points on the graph and graph accordingly.

the difference between a great professor/teacher like this and all the ones I seem to get is that rather then just explaining the "how", he explains the "why" as well. It is so crucial to learning this stuff and I don't know why so many math teachers don't seem to understand it, or maybe they did at one point and just stopped trying as hard. I don't just want to be given the answers without depth so thank you so much for expanding on this.

[brianmclogan]

thankyou for the kind comments, I am always trying to improve my instructional delivery

[brianmclogan]

yea there might be repercussions down the road. Could thing you are ahead of the curve. Nice Job!

[JS-hxcg]

Over the years you alone have completely changed my outlook on math. I used to be too scared to even look at numbers. Truly can't thank you enough.

[brianmclogan]

The period is pi/3 so every x intercept is pi/3 distance from each other

[pabloralda]

Do you have any videos that go over finding the points for graphing tangent graphs?

[noIies]

I believe you can also find the new point by taking the period and divide by 2, and then just keep adding the period to get the other points.

Missed this lesson and asked my teacher how to do it. He acted like I knew how to do it already and was so rude. I want this teacher

[brianmclogan]

haha no worries, we will keep that between you and I. Glad I could help

[brianmclogan]

vertical/horizontal asymptotes? x intercepts for any equation you put zero in for y and then solve for x. To find the y intercepts for any equation put zero in for x and then solve for y

Thank You, Thank You. Your videos has help me in so many ways you can not imagine. THANK YOU 🙏🏽 😊

[hope-tnoz]

I miss having a legendary math teacher like this that just makes you understand a topic so easily. Thank you for being that kind of teacher.

3:00 is there a dog in the classroom? Lol

[gavinbranch]

everything completely just clicked, thank you so much

Stuck doing year 11 methods in lockdown, and this is the only thing that's helping me. Thank you so much Brian!!

Guys if you are working with degrees use: standard period and devide it with b{which is the new values in the brackets of tan(..)}

[endian]

Not a bad video, but probably the worst example and explanation of dividing by three on both sides that I've ever seen 😆 Just multiple by 1/3 both sides and cancel. Simples.

Also, the two graphs should LOOK different - i.e., the tan(3x) graph should be much narrower than the tan(x) graph. What would be even better is to draw the two graphs on the same axes, using different colours, to show precisely how they differ to each other. The tan(3x) graph in this video looks WIDER than the tan(x) graph, which is definitely not what you want students to think!

The part I didn't get was how to find the points...

[Jynxedpop]

thank you so much! I had to take pre calc online and I'm just struggling through but your videos help a ton!
just one question though; how do you find vertical/horizontal as well as the x/y intercept?

[ZoeyQaisar]

i never comment o youtube videos but this was so worth it and so helpful Thankyouu so much !!!!
