U could really connect to people who are slow in maths. It's wonderful how you simplify and emphasize on the key points. Deep respect for you sir.

I'm in calculus 3 and this video is still VERY relevant. I never learned (or was even taught) any of this in the TWO PreCalc classes I took and it really came back to bite me during Calc 1 and 2. Thanks, Professor!

I am now in my junior year in electrical engineering but I still watch your videos to keep me fresh. You are a gentleman and a scholar, truly. Thank you so much.

Love your videos. Please do a series on linear algebra. My Soul will thank you for eternity. Love you prof!

when I finish college I will be owing those youtube supermen and superwomen a lot! you saved me in high school and you are saving me again right now. I wish you get what want in life just like you allowed us to get what we wish by these videos

*Handy tip:* The curve on the graph will bend one time less than the exponent in the function. x^1: Doesn't bend at all. Straight line. x^2: Bends once. x^3: Bends twice. x^4: Bends three times. x^5: Bends four times. And so on.... :)

Even functions all have parabolic shapes, thus they bend similarly

that's how many times it *can* bend, not how many times it always will

I’ve been very appreciative how much work you put into this. I’m review my pre calc before this fall semester. I have calc 3 and Modern diff eqs. Kinda crazy haha thank you once again

Using all the best, positive and wonderful from the dictionary won't be enough, I can just say that I'am and will be grateful for ever. Thank you Professor Leonard, may GOD bless you and all that you love and care about.

Thank you once again Professor Leonard. You are phenomenal

thank you so much for the incredible lessons.

Professor Leonard, this lecture analyzes the graphs that all students in science and engineering students should know. Students should have a deep understanding of these graphs and their impact in mathematics.

You are a lifesaver! I feel like a genius listening to you!

What an amazing guy you are.

Quality lookin' sharp! What kind of camera do you use?

thanks a lot sir . u r helping masses in learning mathematics.

Thank you king! I have hope for myself in college algebra now 😭😭😭

Brilliant video

Love your videos! Please do a series on linear algebra.

Big fan your way of teaching sir..just made sem easier!!!love from india

great summarize!

thank you so much sir. you really helped me

Thank you for actually explaining why the graphs are shaped the way that they are. This was not explained to me while taking college algebra. Now I am better prepared for calculus.

DEAR PROFESSOR LEONARD, YOUR VIDEOS HAVE HELPED ME GET THROUGH HIGH SCHOOL AND COLLEGE. I’VE JUST STARTED LINEAR ALGEBRA AND I’M STRUGGLING GREATLY. THE TEXTBOOK IS ASKING ME ABOUT QUESTIONS THAT IT DIDN’T EVEN DO ANY SAMPLE QUESTIONS ON. PLEASE DO A SERIES ON.. INTRO TO SYSTEM OF LINEAR EQUATIONS. I NEED HELP WITH FINDING SOLUTION SET OF EQUATION(S) WITH MULTI-VARIABLE EQUATIONS SUCH AS ** x - 2y + 3z = 5** etc

Love your video Professor Leonard! You have helped me a lot this semester. Next semester I will be taking Elementary Calculus. What serious would be best for me to study before going in to it?

THANK YOU!!!!

Thank you

I failed in Math(Calculus) in college because I took different field not related in STEM when I was in middle school. Now I'm here to finish all this course to fight back and pass that Calculus subject. Next I would take the Calculus course together with some textbook that I found in the internet.

Very understanding

Hi sir please make the video on LINEAR PROGRAMMING PROBLEM...THANK YOU

You're literally superman teaching us math

Fantastic

Damn, camera quality looking nice

In INDIA we call Guru to a teacher, We touch their feet to give respect. Every time I see your video It simply comes from my heart to touch your feet. That has never happened to me throughout my life. You are simply amazing. I had a feer of Mathematics. Now it's gone. Thank you.

Me being "math illiterate" Prof: Does that make sense to you? Me: uhhhh... It is getting better but I still have a long way to go.

This dude is a LEGAND,

I hope he gets back to differential equations. :D

Well, I was surprised when I landed in this challenge. Is Superman teaching us math? Yes, he is.. Thanks for all math helps. Professor Leonard

Professor actually I can’t understand how you take the curve of the graph.please can you explain it to me. That will be a great help!

i love u man

Thank you for spelling asymptote. Ive been spelling it acentote this whole time 😅😅😅

please upload the transformation video!!

Professor, sorry for asking you here, but i can't find Calc 3 Lecture 14.5 video, is it missing or just it's just an listing mistake ?

Question for students: Is function f(x)=b ever going to be odd function?

I’m really getting into your videos to make custom indicators for forecasting in the stock market and I gotta say you look just like me man we could have been clones you’re probably about 10 years older than me I’m 25 I wish I would have taken math more seriously

Saved this vets life.

x^2 is an even function parabola graph, 1/x is an odd function hyperbola graph.... so Professor Leonard what about 1/ (x^2) ? What is it ?

I wish I could take him for my college math teacher but, I live in NYS.

I am speechless

Any updates for differential equations?

I am also curious about this.

1/x still fit -f(x) = f(-x) yet i said its not odd because it doesn't go through the origin, so which is it? does odd function need to cross the y-axis as while to be odd?

@pkus

Жыл бұрын

it does not need to be go through the origin instead its has to be symmetric of the origin. Anyways, in other way we can prove that f(x) = 1/ x is odd function, f(-x) = 1/(-x) = -1/x = -f(x) so its odd function

I can't remember shapes of graphs. I can remember what defines the shapes. All but 2 of the graphs are variations of f(x)=x. f(x)=|x| is a piecewise function where y for -x is inverted. Most of the rest are described by the exponents of x. Square and cube roots are fractional exponents. The farther the exponent is from 1, the sharper the curve of the graph at its apex giving a more squared off line. The larger the exponent, the more the apex of the curve will move away from (1,1) toward the x axis making the line more vertical. The smaller the fractional exponent, the more the apex of the curve will move away from (1,1) toward the y axis making the line more horizontal. For function with x as the denominator, y is the reciprocal of x. I would love to see a video showing this and tying in transformations as a way to further tweak the line that exponents or a fraction created.

Can someone explain me That how does cube root of -1 is -1 . It should be an imaginary no. So there should not be any point in graph

@paky3052

-1 * -1 * -1 = -1

Root is the opposite of exponent. Try raising -1 to third power: (-1)^3 = -1 * -1 * -1 = 1 * -1 = -1

but the output of negative roots are not real numbers that's what you told in previous videos

sir looks like Henry Cavill 😂😂😂😂

One request.. at the end of the video, if you could stand aside it would be helpful to take the screenshot

Graph you must know: Граф Монте Кристо.

Not true, x^n will have at most n-1 turning points. Note x^4 x^6 can look similar to a parabola
