Arithmetic Progression

These formulas will help students solve all the Arithmetic Progression questions. The chapter "Arithmetic progression" is a very scoring topic. If you are thorough with these formulas and practise them, you can score good marks.

The formula to calculate the nth term of AP is given as:

nth term = a+(n-1)d

The sum for the nth term of AP where a is the 1st term, d is a common difference, and l is the last term is given as:

Sn = n/2 [2a + (n-1) d] or Sn = n/2 [a + l]

Linear Equations

The linear equations have tremendous applications in various fields and assist in problem-solving. These formulas that will help students solve all the linear equation questions. These formulas will help you solve those questions effectively.

Linear Equation in one Variable	ax + b=0	Where a ≠ 0 and a & b are real numbers
Linear Equation in Two Variables	ax + by + c = 0	Where a ≠ 0 & b ≠ 0 and a, b & c are real numbers
Linear Equation in Three Variables	ax + by + cz + d = 0	Where a ≠ 0, b ≠ 0, c ≠ 0 and a, b, c, d are real numbers

When two variables are given:

a1x+b1+c1=0 and a2x+b2+c2=0
Where a1, b1, c1, & a2, b2, c2 are real numbers & a12+b12 ≠ 0 & a22 + b22 ≠ 0

• cos (90° – θ) = sin θ

• tan (90° – θ) = cot θ

• cot (90° – θ) = tan θ

• sec (90° – θ) = cosecθ

• cosec (90° – θ) = secθ

• sin^2 θ + cos^2 θ = 1

• sec^2 θ = 1 + tan^2 θ for 0° ≤ θ < 90°

• Cosec^2 θ = 1 + cot^2 θ for 0° ≤ θ ≤ 90°

Algebra & Quadratic Equations

These formulas will help students solve all of the Algebra & Quadratic Equations questions. The formulas may seem a little lengthy, but once you are through them, you will quickly learn them, you will be able to score good marks in this chapter.

1. (a+b)2 = a2 + b2 + 2ab
2. (a-b)2 = a2 + b2 – 2ab
3. (a+b) (a-b) = a2 – b2
4. (x + a)(x + b) = x2 + (a + b)x + ab
5. (x + a)(x – b) = x2 + (a – b)x – ab
6. (a + b)3 = a3 + b3 + 3ab(a + b)
7. (a – b)3 = a3 – b3 – 3ab(a – b)
8. (x – a)(x + b) = x2 + (b – a)x – ab
9. (x – a)(x – b) = x2 – (a + b)x + ab
10. (x + y + z)2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
11. (x + y – z)2 = x2 + y2 + z2 + 2xy – 2yz – 2xz
12. (x – y + z)2 = x2 + y2 + z2 – 2xy – 2yz + 2xz
13. (x – y – z)2 = x2 + y2 + z2 – 2xy + 2yz – 2xz
14. x3 + y3 + z3 – 3xyz = (x + y + z)(x2 + y2 + z2 – xy – yz -xz)
15. x2 + y2 =½ [(x + y)2 + (x – y)2]
16. (x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
17. x3 + y3= (x + y) (x2 – xy + y2)
18. x3 – y3 = (x – y) (x2 + xy + y2)
19. x2 + y2 + z2 -xy – yz – zx = ½ [(x-y)2 + (y-z)2 + (z-x)2]
