+## Jumped To Brush up Linear Algebra | Day 26
+Found an amazing [channel](https://www.youtube.com/channel/UCYO_jab_esuFRV4b17AJtAw) on youtube 3Blue1Brown. It has a playlist called Essence of Linear Algebra. Started off by completing 4 videos which gave a complete overview of Vectors, Linear Combinations, Spans, Basis Vectors, Linear Transformations and Matrix Multiplication.

+
+## Jumped To Brush up Linear Algebra | Day 27
+Continuing with the playlist completed Next 4 Videos discussing topics 3D Transformations, Determinants, Inverse Matrix, Column Space, Null Space and Non-Square Matrices.

+## Essence of calculus | Day 30
+Completing the playlist - Essence of Linear Algebra by 3blue1brown a suggestion popped up by youtube regarding a series of videos again by the same channel 3Blue1Brown. Being already Impressed by the previous series on Linear algebra I dived straight into it.
+Completed about 5 videos on topics such as Derivatives, Chain Rule, Product Rule, and derivative of exponential.
