Test your understanding of the content covered in the video with some practice exercises courtesy of ProPrep. You can download the workbooks and solutions for free here: api.proprep.com/course/downlo...

As with all modules on ProPrep, each set of videos contains lectures, worked examples and full solutions to all exercises.
The video begins with the definition of the kernel and image of a linear transformation, as well as their dimensions as the nullity and rank of the linear map. Next is a fully worked example of a map in R^2 with an explicit calculation of the kernel, image, nullity and rank.
In the second part of the video the Rank Nullity Theorem is presented: the dimension of the starting vector space of a linear map is equal to the rank of the linear map (dimension of its image) plus the nullity of the map (dimension of its kernel). A full step-by-step proof is then presented by constructing a basis for each component.

Hi Dr Tom found a little bit of random maths for you in this cartoon series 'Teenage Mutant Ninja Turtles Season 2 Episode 21 - April's Artifact' (SKIP TO 13:45 to 14:15) ua-cam.com/video/Gs9E8i2-fqs/v-deo.html
he doesn't look like a guy who would do maths, but he is a really nice and smart guy
The best rank nullity theorem video I have ever seen ;)
You are a great teacher 😊
Sir .. please make a lecture on how to extend a basis to another basis ...
Did you test 10 to see if 11 was, indeed, the minimum number needed?
Hey dr tom
You teach in oxford??
OMG, that amazing
What is?
you should make a video about jee advance soon
Sir can you solve
Jee advanced maths question paper ?
I thought I could learn something but I'm too young to understand this :Σ
دلم خواست
I think finish
but my color is pink
because is He
Bad hair day again 🫤
I'm on that side of UA-cam again
