Equation for parabola from focus and directrix | Conic sections | Algebra II | Khan Academy

Missed the previous lesson?

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

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.

Because of this parabola I lost my childhood and teenage days

[ryannmunoz]

Everytime I struggle with my algebra, I come here. I do online school so it's hard to move forward when I'm stuck without my teacher getting back to me (especially since I'm a night owl. I normally have to wait until the following day). Thank you! I'm bad with numbers but when I watch these videos they (sort of) make sense.

when your teacher gives you a question on a test that he has never covered...

Sal: it's free real estate

[florencecuomo]

"hairy algebra"
can we just

[charmendro]

5:20 "Let me give myself a little bit real estate over here" lol

[ryanio]

Really fantastic Sal. Thank you so much.

[甘木-mr]

Define childhood do I remember parabolas from my childhood? ✨📚🍨🍉

[GiuseppeLospalluto]

Thank you so much man ! You are fantastic

[nikhilverma]

Thank you! I was in need of such a video for computing voronoi diagrams in my project

[amazingunseen]

Thanks Salman khan to create this Educational Organization!

Which software do you use to write everything?

[alextrezvy]

The link under (Missed the previous lesson?) is broken.

How do I find the equation of the ellipse given only that the the major axis is vertical and the graph passes through the vertex of a parabola?

[azrielsshadowsinger]

my brain can’t handle this- what did he just do

[patrikchristian]

what if the equation of dirctrix includes 'x' also?

[kevinpena]

does anyone have answers to a sheet where we have to solve questions and its called the Focus and Directrix of a Parabola and its a leprechaun drawing on the back

[padme]

for what grade is this mainly on? like 8th, 9th, 10th etc.

[big-pp]

Take a shot for every “hairy algebra” 😂

[jimbernabe]

I watched another video regarding this. It demonstrated another formula (y-k)^2=4p(x-h) Is this formula applicable?
