Here you will find the video tutorials for class 11 Mathematics.
Class 11 - Chapter 1 - Sets
This tutorial cover more than 50% percent of Sets, Chapter 1, of class 11 mathematics. The other half will be added once ready.

Class 11 - Chapter 2 - Relations (One-shot video)
This chapter has been split into 2 parts :
- Relations
- Functions
The reason is to cover this chapter in depth so that it should be helpful for students who are willing to appear in competitive exams as well.
Below embedded is a one-shot YouTube video that covers the Relations section in detail.

🔥 Coordinates of a point on (1) Circle of radius r (2) Unit circle || Prove that sin^2x + cos^2x = 1
Formulas "sin(2npi + theta) = sin theta" and "sin[(2n+1)pi – theta] = sin theta"
Proof of (i) cos(- θ) = cos θ, (ii) cos(2npi + θ) = cos θ, (iii) cos(2npi – θ) = cos θ | Unit circle

Prove that 🔥 cos (x + y) = cosx cosy – sinx siny 🔥 Full derivation by #mathemafia
Prove that 🔥 cos (x – y) = cosx cosy + sinx siny 🔥 Simple proof by #mathemafia
cos (pi/2 – x) = sin x 🔥 sin (pi/2 – x) = cos x 🔥 Solved trigonometric identities by #mathemafia
Prove that sin(x+y) = sinx cosy + cosx siny 🔥 💁👌😍 🔥 and sin(x-y) = sinx cosy – cosx siny
Prove that (i) sin(pi+x)=-sin x (ii) sin(pi-x)=sin x (iii) cos(pi+x)=-cos x (ii) cos(pi-x)=-cos x
tan(x + y)=(tan x + tan y) / (1 – tan x tan y) 🔥 & 🔥 tan(x – y)=(tan x – tan y) / (1 + tan x tan y)
cot(x + y)=(cot x cot y – 1)/(cot x + cot y) 🔥 & 🔥 cot(x – y) = (cot x cot y + 1)/(cot y – cot x)
Proof of sin 2x = 2 sinx cosx = 2 tan x /(1+tan²x) where x is not an odd multiple of pi/2 🔥
Proof of cos 2x = cos²x – sin²x = 2cos²x – 1 = 1 – 2sin²x = (1 – tan²x) /(1 + tan²x)
Proof of 🔥 tan 2x = 2 tan x /(1 – tan²x) 🔥 Class 11, Trigonometric Identities by #mathemafia
Proof of three trigonometric identities 🔥 sin 3x, cos 3x and tan 3x 🔥 by #mathemafia
Easy proof of 🔥 sin x + sin y 🔥 cos x + cos y 🔥 sin x – sin y 🔥cos x – cos y by #mathemafia
Thank you sir kindly tell about approach to class 11 maths curriculum
My approach is quite simple, read every word of the book that you are following. The video tutorials will help you get along quickly but the amount of knowledge available in books is unmatched. A timetable and a short-term and long-term plan are always helpful. You can use free software available for time management and tracking. Good luck with your studies. Cheers!!!
