Great vid.
Hey sir, I really appreciate work and watch ur every videos. Can u make about triangular prism questions?
Can u use calculator for the last question
Yes, if you have a calculator that supports simplified radicals then you could input your expression for L.
@DrewWerbowski Thank u so much 💓
Awesome Tutorial, And Awesome Tutor 👌
Thanks bro
Handsome boy
Handsome bit
you should do videos on a black page with white text. Kinda kills the eyes. Great content in the video much appreciated
I appreciate the feedback! Will definitely consider that for future videos.
i cant wait for the ENEM version
GeForce Game Ready Driver is AVAILABLE 🗣🗣🗣🗣‼‼‼‼‼‼
Thank you 🙏🏼
Math exam before an hour here , thanks
my goat <3
THANK YOU FOR EXPLAINING HOW YOU ARE DETERMINING WHICH VARIABLES ARE FREE. Did not know it had to do with which columns had a pivot. My final is Monday at 7am, will keep watching your videos 🫡
thank you so much!!!!
The second can be done with desmos! just plug in the equation, then set x = 1 + square root of k and plug in the answers provided until one matches the positive solution. However, this can only be done if it's a write-in question. If that is the case, take the positive solution that you see on the graph minus one and then squared and you have the solution. This method may be even more efficient.
Can you please consider making vids on probability and statistics ? I have a course on it next semester and your teaching would be very helpful.
i'm confused, would the third question not be solved using discriminants? because it says No solution?
it is not a quadratic equation. It is linear
okay i got the concept, but i still can't figure out how you find the basis, in what reason do you choose [2/3 1] as the basis of the eigenspace when the eigenvalue is 4, the same way with the eigenvalue equals to (-1). pleasee i need help, my final is soon!!
I haven't seen such an easiest way of solving maths problems.It seems like u r playing on ur computer. By the way Brother ur vocal delivery is truly captivating
Can you explain how can I know if the vectors are free or not? how can i know that they're not equal to 0 and they're linearly dependent? it's as what is said in 10:42 I really can't figure it out, i still have difficulties😭😭
how do you know which lambda is first and which comes next? When you number them lambda 1 and 2? Thank y9ou.
Usually it is in increasing order of eigenvalues from most negative to most positive
for 12:13, how did you know to assume that triangle BAC was a right triangle? was it just a visual assumption or is there a ratio/rule that you used to determine that?
It's not an assumption. Although he didn't mention it, he invoked Thales's theorem, which is a special case of the inscribed angle theorem: 'If X, Y, and Z are distinct points on a circle where the line XZ is a diameter, the angle ∠XYZ is a right angle.'
Because its a semicircle, its angle at the circumference is 90 degrees
How much would i get if i got 3 difficult questions wrong.
The last question can be solved even simpler. Take the equation, plug in desmos. Find x values. Remember when u set the solution = 0, k will be positive. so set the positive solution I think it was 0.414 when I graph to the sqrt k - 1 and solve for k. Dont need complex math
Thank you, this is helpful ❤
Thank you so much!
awesome! this was super helpful
Didnt you teach at my school?
For the first one the gradient is negative but you drew a positive slope
your the goat bro
By doing what from the previous exponents got you 15/2 as x (like from 5/2 and 1/3).
you can use log (2/3) (b), which makes x the subject
you are jesus
Hey, is the range of a linear transformation the same as find the image of linear transformation?
Yeah
Good video
You are single-handedly saving me with Linear Algebra, thank you.
Bro why did my prof give me hocus pocus tricks to use to convert?? Like it’s so easy
Really great explanation! Love how you went through it so methodically.
Thanks for the comment! Glad I could help!
taking differential equations rn and u just saved my life
🎉
you made it much easier and i can say you made it more easy than the professors of india's highest ranked iit
Thank you for your video! Some of the questions in the video actually came out in the real exam yesterday! I hope I did well. Thank you so much for making this video!
Im so confused with the first question
Since we're dealing with a parallel line Vs parallel plane, wouldn't it be easier to choose the position vector of that line and treat the whole problem as if you're dealing with that one specific point? because the distance between the line and the plane will be the same throughout anyways...
The first question could be done in an easier way if you know about logs
honestly plug it into desmos, way easier and less icky math
@@AmrutaVelamuri yea or just do it with your regular calculator, and log base 2/ 3 it. idk why he made it seem a bit too complicated not like we have a non calc section
@@AmrutaVelamuri what do you plug in?
@@nirmalkusunuri4240 how
@@senshinra First solve for B with the first equation, set b as x in this context and solve. After that do (2/3)^( x)=the b value you have. This way you dont need to actually any of the calculations
Bro you predicted the question no 5 but question was to find the a+c
So useful, thabk you so much!!
