Graphing the Tangent Function with a New Period

Рет қаралды 243,823

Күн бұрын

👉 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.

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

@ericmontiel3234 3 жыл бұрын

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.

@moonsmien 2 жыл бұрын

This!! I never really get to fully understand something unless I learn exactly why it happens as well. You just get to conceptualize more and grasp the topic better if you're actually aware as to _why_ something happens instead of just _how_ . You can also apply these things easier that way to other types of situations as well.

@jennahalcomb7359 2 жыл бұрын

Yes! Because if you explain why then we can use logic to remember it, but if you don’t then it’s just memorization.

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.

you can do it another way but I like to do it that way as those as the asymptotes of the initial period for tangent

@Aurora-pp3cs 6 жыл бұрын

I wonder, why don't we have x scale? Aren't we supposed to divide the period by 1/4 as we are doing for sine cosine graph? Also if I find the x scale; it will be "4pi/3" so between each critical point the distance will be "4pi/3" but here it is "pi/3" and that's just the period.

@brianmclogan 6 жыл бұрын

you can make the x-scale however you like, while making the x-scale by 4ths is most common, I simplified it to halves since those are where the critical points occur

Why is it that in some videos, to find the endpoints/ asymptotes you use (bx)=0, (bx)=pi and in others you use what you did here (bx)=-pi/2, (bx)=pi/2?

Hi, I like your video however it would it not be easier to state that the period of the graph is pi/3 and when you divide the period by 2 you get pi/6 which is where your asymptote will be on the right and then -pi/6 on the left.
