We at Embibe have covered all the formulas of Maths Class 10 NCERT PDF to help with your exam preparation. This exam is of 3 hours duration, and in order to manage this available time well during the examination, you must be aware of all the important concepts and their formulas.

Learning math is time-consuming because of the need for problem-solving and calculations. To learn these 10th Class Maths formulas, students can use PDFs created by Embibe. Before getting into the list of the formulas, let us check out the major chapters of Class 10 Maths for which formulas are needed:

Class 10 Maths Formulas for Arithmetic Progression (AP)

If a1, a2, a3, a4….. be the terms of an AP and d be the common difference between each term, then the sequence can be written as: a, a + d, a + 2d, a + 3d, a + 4d…… a + nd. where a is the first term and (a + nd) is the (n – 1) th term. So, 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]

Class 10 Maths Formulas for Linear Equations

Linear equations in one, two, and three variables have the following forms:

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

The pair of linear equations in two variables are given as:

a1x+b1+c1=0 and a2x+b2+c2=0

Where a1, b1, c1, & a2, b2, c2 are real numbers & a12+b12 ≠ 0 & a2+ b22 ≠ 0

Quick Note: Linear equations can also be represented in graphical form.

Trigonometry Formulas for Class 10 Maths

The Trigonometric Formulas for Class 10 cover the basic trigonometric functions for a right-angled triangle i.e. Sine (sin), Cosine (cos), and Tangent (tan) which can be used to derive Cosecant (cos), Secant (sec), and Cotangent (cot).

Let a right-angled triangle ABC be right-angled at point B and have \(\angle \theta\) is one of the other two angles.

sin θ = \(\frac{Side\, opposite\, to\, angle\, \theta}{Hypotenuse}\) = \(\frac{Perpendicular}{Hypotenuse}\) = P/H

cos θ = \(\frac{Adjacent\, side\, to\, angle\, \theta}{Hypotenuse}\) = \(\frac{Adjacent side}{Hypotenuse}\) = B/H

tan θ = \(\frac{Side\, opposite\, to\, angle\, \theta}{Adjacent\, side\, to\, angle\, \theta}\) = P/B

sec θ = \(\frac{1}{cos\, \theta }\)

cot θ = \(\frac{1}{tan\, \theta }\)

cosec θ = \(\frac{1}{sin\, \theta }\)

tan θ = \(\frac{Sin\, \theta }{Cos\, \theta }\)

The Trigonometric Table comprising the values of these trigonometric functions for standard angles is as under:


Some other trigonometric formulas are given below:

  1. sin (90° – θ) = cos θ
  2. cos (90° – θ) = sin θ
  3. tan (90° – θ) = cot θ
  4. cot (90° – θ) = tan θ
  5. sec (90° – θ) = cosecθ
  6. cosec (90° – θ) = secθ
  7. sin2θ + cos2 θ = 1
  8. secθ = 1 + tan2θ for 0° ≤ θ < 90°
  9. Cosecθ = 1 + cot2 θ for 0° ≤ θ ≤ 90°

Class 10 Maths Formulas for Algebra And Quadratic Equations

To know the algebra formulas for Class 10, first, you need to get familiar with Quadratic Equations.

  • (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
