Inverse of a 2x2 Matrix using Adjoint | Don't Memorise

[@InfinityLearn_NEET]

The inverse is defined only for non-singular square matrices. The following relationship holds between a matrix and its inverse: AA^-1 = A^-1A = I, where I is the identity matrix. ✅To learn more about, Matrices, enroll in our full course now: infinitylearn.com/cbse-fullcourse?KZbin&DME&HYWeEx21WWw To watch more videos related to Matrices, click here: bit.ly/Matrices_DMYT

[@sierrasierra1075]

In that case what does it mean when you are given an expression and asked to give your answer as a single matrix? Do you have to get the determinant after you solve the matrix?

[@zee6726]

can anyone like me the video where Don't Memorise explains what exactly are 'row and column operations' and 'elementary operations' are ???? i'm a bit confused

Thank you

sir please make a complete series on calculus......please

[@christinenillosguin906]

is there a video where it can be applied with 3x3 or more?

[@7odaifa_ab]

why i could not find the Elementary operation videos ?

How do we find adjoint of a matrix?

[@RodwellHamoonga-jw2ks]

What if both sides are negative sins

Your every single video is incredible ♥️, the way you give the concept is absolutely awesome:))

How can i calculate inverse of 2x2 matrix without using shortcut method to find out adjointA. I want to understand how adjointA of 2x2 matrix through the long route.

[@hambonefakenamington69]

wow now i don't need to sit for a tedious lecture. i already know half of the chapter

[@moumitarai1647]

Amazing! Your videos are very helpful and easily understandable.👍

[@Tedex7650]

It's wrong explanation dear because you still forgot transpose of adjA matrix please correct it otherwise more people learn wrongly from your video...Just correct it dear... Otherwise no problem in this explanation...

[@usmanjavaidkhan]

Amazing Piece of work. Nice way to get the things clear. #Subscribed ♥

[@InfinityLearn_NEET]

Welcome to the Don't Memorise family :)

[@usmanjavaidkhan]

My pleasure ♥

[@kabouch]

Why do we sometimes have to get the multiplicative inverse of a matrix? Because matrices could be only added, subtracted, or multiplied, but not divided. To divide A/B, one has to get the inverse of B first then multiplies A by the inverse of B.

When the answer is 0 and how to do

[@meghakataria5091]

If our determinant comes 0 then we will not proceed that question as it goes invalid.

[@dchemistry7978]

Give inverse of 3x+4y=11 2y-y=1
