Tangent graph | Graphs of trig functions | Trigonometry | Khan Academy

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Thank you Khan Academy for continuing to educate people at zero cost.

This explains it in a way for me to understand what I am doing and not blindly trying to plot dots on the graph.

[TheDeathlure]

Maybe do something talking about the shifts of tan. Or looking more at how to graph an actual equation with tan.

[MuraNutkar]

Thank you soo very much for the video, without the video I wouldn't have been able to understand how to graph tangent for my test. This is was easy to understand. So thank you so very much, this will prevent me from failing.

[himaniagnihotri]

thank you khan academy...finally I understood it

[rushilpatel]

Continue this good work Khan Academy.... love you! You deserve recognition, and you will get it! Thank you from the bottom of my heart!

[amandamoore]

This helped me understand this function so much more

[donghyukoh]

as we approach 3pi/2 we reach a positive infinity???? shouldn't it be a negative infinity?

[sinkr]

i don’t understand at all how he got -pi/4 and pi/4. i don’t understand how he got his asymptotes or anything of that nature. he doesn’t explain his steps.

[rottis]

thanks man, i literally was so confused about what tangent function was

[CrisMartinez]

So how would you graph y=A tan (wx) + B say for example y= 5 tan x - 2

[ea]

And that's only the parent function folks!

[itsjessa]

ayo whoever is speaking needs to make a separate channel for asmr 🥴

[jayceinfinitealgharhythmns]

At 3:15 how did you determine it equals to one?

[Naruto_Uzumaki_]

I can't believe all of this is for free

[Toadi_]

my head feels like it’s going to explode

[manutavano]

I know I'm late to the party, but thank you!

[jessicasingh]

Sal I wish you were my trig professor ☹️

[michaelcomerford]

What is the period of the graph of the tangent function

[AndaleMarrana]

this is so difficult for me to grasp atm...
