Muy bien excelente

If my college lecture was this small I would attend it everyday

Genius guy

I like it. As a teacher, I think the old way is too complicated for the distracted mind.

Why you can split to two right angled triangle and add the two.

That's way too easy for SAT. It is 9th Grade Math.

12x^2 + 16x + 6 Pls solve

Bullshit! Stronzate! Ma l'asilo Mariuccia al tuo paese l'hai superato occhia mandorla?

But what if both try to eat more and eat quickly

bodmas comes in clutch

How many people accidentally square or power to 4 the 7 on the other side.

Here in Bangladesh, we learned it in 7th grade!

Damn bro got that tricep by just writing on the board

Bro Heron must have come up with this after I graduated

Very nice

You mean -3² = -1* 3²= -9

Imagine a pizza with 60 equal slices. Tom can eat it in 20 minutes which means he eats 3 slices per minute. Similarly Mike eats 2 slices per minute. Together they eat 5 slices per minute. To eat 60 slices, it would take them 12 minutes

I will teach this rule next year to my students. Thanks.

21/6×10 ~> 21×1.66....= 21+14= *35* or 7/2×10 ~> 7×5= *35* !! 🇪🇺👍🤙💪

A convenient alternative to factoring a trinomial. Thanks

I wish I had more math teachers like you!

He is teaching in a pakka manner

The question is not "what are the square roots of 4" (only 2!!!, it is a term, for example f(4) (in R+) with f the square root function defined on R+ (bijectivity!)). It is "what are the solutions to the quadratic equation x^2=4" (x=2 [exclusive] or x=-2) which has 2 solutions in R... because x maps to x^2 is not even injective as a function defined on R Bonus: let f be x maps to x^2 with domain and codomain... R+ to R+ (bijective = injective and surjective, inverse function is (the positive/principal branch of) the square root function) R+ to R (injective, not surjective) R to R+ (surjective, not injective) R to R (neither injective nor surjective)

Won't the square of "-ve" become "+ve" because "-"×"-"="+"

Heye korute tor jibon tuh jabo billa

x = 4*i^4 - 1 would work; taking the square root of x +1 would give 2*i^2 or -2.

I love the crust. I get 24 units of crust with the two pizzas and only 18 with the single pizza. Always clearly define your problems.

that looks quite easy but i assume this will help many people

Answer is 7

Sir, please upload some videos on integration.

No, simply divide x + y by xy to quickly obtain 1/x + 1/y, then this must also be equal to 10/20 = 1/2

Used log2 for answer 3/4

THANKS A LOT SIR!

This is derived by using derivatives Let f(x) = √x, x = 100. ∆x =+2 f(x+∆x) = ∆x.(df(x)/dx) + f(x)

You are a hardworking peron ❤

The right way to solve this is to multiply both sides by (x-2)^2. Since (x-2)^2 is always positive, it does not change the inequality sign.

Grade 8-9 problem

This is very informative @mr H .......try open another online platforms for maths questions.....very nice work done sir

Wikipedia explains it's derivation. You can figure it out using the Pythagorean theorem making this triangle into two right triangles, with the shared side = x, and the 7 meter sides = y and 7-y, etc etc. Its an elegant formula from thousands of years ago.

Sir can you solve math problems of jee mains and jee advanced

Our math teacher never taught us such details of logs
