Maths Formulas for Class 10: Memorising formulas in Class 10 Maths is difficult. Students tend to become nervous and forget the formulas. These formulae lay the mathematical foundation for high school and college entrance exams. Students who memorise formulas well tend to score better marks in Maths exams. Formulas in Class 10 help students solve mathematical problems with greater accuracy.
In addition to Maths, these formulae can also be applied in various fields. Students can also use the chapter-by-chapter Maths Formulas for Class 10 to prepare for the board exams. We advise students to download the PDF of these formulas to refer to them offline while studying for exams. Below we have provided all the necessary details related to Maths Formulas for Class 10.
Maths Formulas for Class 10: Chapter-wise
Compiling all formulas of Class 10 Maths is not easy for the students. However, it is essential to score well in the Class 10 board exams, and Maths is one of the compulsory subjects in Class 10 in which students can score well. This exam is out of 100 marks and covers all the basic topics of Mathematics.
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:
Linear equations in one, two, and three variables have the following forms:
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
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 & a22 + 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 is right-angled at point B and have \(\angle \theta\) is one of the other two angles.
