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

sin(nπ)=0 and cos (2n+1) π/2 = 0 | Explained with unit circle

All School To College | ASTC Formula to remember the sings of trigonometric ratios in 4 quadrants

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
