Great video thanks sm

Just want to say thanks for helping me learn so much so quickly as I prep for the middle school math test for my license!

I feel so sad that I’m in calc 2 and needed to watch this for polar coordinate Cartesian equations 😂

Im a sophomore in high school and the teacher writes everything so sloppy and goes too fast. You explain it very carefully. Now i dont have to worry about failing my semester exam. Thanks man!

thank you sooo much

What if y or x is just the square root of something

thankyou

Its amazing how you condensed a hour long class into two minutes while still managing to explain everything in a clear and concise manner. Great stuff man.

THANK YOU SO MUCH!

How do u find it if they didn't give the hypotenuse

THANK YOU MR. MARIO

Let’s just say you sir just saved my math grade. Thank you so very much👍👍👍

thank u Mario

but your princess is in another castle.

I feel like we learn better when we watch videos then being taught because we are desperate and want to know how to solve said problem and so your brain (MAYBE IM NO SCIENTISTS)goes into ultra learn more and helps us understand better

Thank you so much. I cant see the board even when siting in the front of the class, i had so much trouble and you made my life so much easier

I’m still confused

Omg so i was stuck on my math for 30 straight minutes and I looked up a video about it…. just so happens to be this one and I GOT A 88!!!!!!!!! For me that is really good by i suck at math so thank you Mario….thank you

Thank youuuuuu

I can’t see shit because of his body covering the white board

Thanks 🤝

Let me know how many indians are here👇👇

Thank you so much, you’re a lifesaver!

my geometry teacher could never

That's so helpful on my module on how to do it…… great!I know it now thank u so much …keep it up sir

OMG LITERALLY THANK YOUUUU

i only have x and 45° but that’s it. idk what to do. there’s also a triangle on top of it that has a leg of 7 and 60°

Wait is the 45-45-90 always gonna be an isosceles right triangle since the legs will be the same? I’m going into eighth and I haven’t learned this yet 😛

Thank you so much! This makes so much more sense!

❤Thank youuuu!❤

What if the hypotenuse is radical 7 and I’d have to find the leg

this is helping me so much in qurantine

You’re an absolute legend Mario!

omfg this is why i did so horrible at math, no real world use to put it in perspective. If i'm building a deck and the hypotenuse is 36" what are the lengths of X and Y?

Thanks man

LITERALLY THE GOAT Kept switching from the 45 and 30 videos for my homework I was so clueless 4 hours ago thanks man

What if the leg has a radical? (3 radical(2)) ? How do I find the hypotenuse?

I always forget little rules like this so I had to come back and relearn it because Geometry is amazing thanks dawg now I can do my homework 💀

thanks bro

Mario, you just saved me

Sir, thank you so much! I have a math test tommorow and I have learned more from your videos than in class. I am genuinely thanking you sir! You have always helped save my grades!!

2 and a half minute video versus a one hour lesson was by far more effective. Thanks a lot!

Quiz tomorrow hope I pass, your videos help so much!!!

Ay man I really appreciate what ur doing for us student✊🏾✊🏾💯💪🏾

thank you!
