## CBSE Class 10 Maths Formulas and Important Equations

Maths is an important and basic subject for the school students and most of the students also consider it as a tough subject as well because of its practical nature. This is a subject that includes a lot of formulas that are used for problem-solving and that too requires a lot of practice to become a master in Maths concepts and their formulas. Think of a question related to the area or volume of any object. You can not find out its answers unless you are aware of these formulas. Thus, it becomes very important to learn and revise these formulas regularly if we even talk about basic Maths for Class 10.

### Trigonometry

• 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

• sin2θ + cos2 θ = 1

• sec2 θ = 1 + tan2θ for 0° ≤ θ < 90°

• Cosec2 θ = 1 + cot2 θ for 0° ≤ θ ≤ 90°

### Circles

• Circumference = 2 π r

• Area = 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
