#### 1. (a+b)^2 = a^2+2ab+b^2

####
= (a-b)^2+4ab

2. (a-b)^2 = a^2-2ab+b^2

= (a+b)^2-4ab

#### 3. (a+b)^2 + (a-b)^2 = 2(a^2+b^2)

#### 4. (a+b)^2 - (a-b)^2 = 4ab

#### 5. a^2 + b^2 = (a+b)^2 - 2ab

#### = (a-b)^2 + 2ab

#### 6. a^2 - b^2 = (a+b)(a-b)

For trigonometric formulas for class 10(x) are given. The link is given below
