ChapterWise CBSE Class 10th Maths Formulas
To solve these chapters of class 10th maths, students must learn the formulas as these are the chapters that cannot be solved without knowing the formulas, so before you start practising these chapters, make sure you are aware of all the formulas for class 10th maths. The chapters are as follows:
 Arithmetic Progression
 Pair of Linear Equation in Two Variables
 Trigonometry
 Algebra and Quadratic Equation
 Circle
 Surface Area and Volume
 Statistics
Arithmetic Progression
These are the formulas that 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 practice them, nobody can stop you from scoring good marks.
The formula to calculate the nth term of AP is given as:
nth term = a + (n1) 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 + (n1) d] or Sn = n/2 [a + l]
Linear Equations
The linear equations have tremendous applications in various fields and assist in problemsolving. These are the 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
Trigonometry
These are the formulas that will help students solve all the trigonometry questions. Students are terrified of this topic, but you won't find trigonometry that difficult if you are thorough with these formulas. To score good marks, students must remember these formulas.

Additional trigonometric formulas:
 sin (90° – θ) = cos θ
 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 are the formulas that will help students solve all of the Algebra & Quadratic Equations questions. The formulas may seem a little lengthy, but once you start going through them, you will quickly learn them, and nobody will be able to stop you from scoring good marks in this chapter.
 (a+b)2 = a2 + b2 + 2ab
 (ab)2 = a2 + b2 – 2ab
 (a+b) (ab) = a2 – b2
 (x + a)(x + b) = x2 + (a + b)x + ab
 (x + a)(x – b) = x2 + (a – b)x – ab
 (a + b)3 = a3 + b3 + 3ab(a + b)
 (a – b)3 = a3 – b3 – 3ab(a – b)
 (x – a)(x + b) = x2 + (b – a)x – ab
 (x – a)(x – b) = x2 – (a + b)x + ab
 (x + y + z)2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
 (x + y – z)2 = x2 + y2 + z2 + 2xy – 2yz – 2xz
 (x – y + z)2 = x2 + y2 + z2 – 2xy – 2yz + 2xz
 (x – y – z)2 = x2 + y2 + z2 – 2xy + 2yz – 2xz
 x3 + y3 + z3 – 3xyz = (x + y + z)(x2 + y2 + z2 – xy – yz xz)
 x2 + y2 =½ [(x + y)2 + (x – y)2]
 (x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
 x3 + y3= (x + y) (x2 – xy + y2)
 x3 – y3 = (x – y) (x2 + xy + y2)
 x2 + y2 + z2 xy – yz – zx = ½ [(xy)2 + (yz)2 + (zx)2]
Circle
These are the formulas that will help students solve all the circle questions. The "Circle" is a chapter where you have to measure the dimensions according to the question. These formulas will help you solve the problems quickly.
 Circumference of the circle = 2 π r
 Area of the circle = π r2
 Area of the sector of angle θ = (θ/360) × π r2
 Length of an arc of a sector of angle θ = (θ/360) × 2 π r
Surface Area & Volume
These are the formulas that will help students solve all of the Surface area & Volume questions. Like circles, these formulas will help you calculate different shapes according to the questions.
Statistics
These are the formulas that will help students solve all the statistics questions. Statistics are all about formulas. Once you are thorough with the formulas, you will be able to solve every problem quickly.
