**What’s trigonometry? Definition of Trigonometry |****trigonometry** It’s the department of arithmetic during which triangles and polygons fashioned from triangles are studied.

That’s, trigonometry is that department of arithmetic during which the connection between the three sides and angles of a triangle is studied.

Trigonometry Formulation for Class 10 | trigonometry formulation class 10

**Trick:- LAL/KKA**

* sinθ = hypotenuse/hypotenuse , cosecθ = hypotenuse/perpendicular

cosθ=base/hypotenuse, secθ=hypotenuse/base

tanθ= perpendicular/base, cotθ= base/perpendicular

* tanθ = sinθ/cosθ , cotθ = cosθ/sinθ

* sin theta × cosec theta = 1

sinθ = 1/cosecθ , cosecθ= 1/sinθ

* cosθ × secθ = 1

cosθ = 1/secθ , secθ = 1/cosθ

* tan theta × cot theta = 1

tanθ = 1/cotθ , cotθ = 1/tanθ

* sin(90-θ) = cosθ

cos(90-θ) = sinθ

tan(90-θ) = cotθ

cot(90-θ) = tanθ

cosec(90-θ) = secθ

sec(90-θ) = cosecθ

* sin(-θ) = – sinθ

cos(-θ) = cosθ

tan(-θ) = -tanθ

cosec(-θ) = – cosecθ

sec(-θ) = secθ

cot(-θ) = -cotθ

trigonometry identities class 10

1. sin²θ + cos²θ = 1

2. tan²θ+1 = sec²θ

3. 1+ cot²θ = cosec²θ

these three **trikonamiti sarvsmikaen** and these **trigonometry all equations** With the assistance of this picture, you possibly can simply bear in mind the formulation made from Use a optimistic signal (+) to maneuver from high to backside within the route of the arrow and a unfavourable signal to maneuver from backside to high in the wrong way of the arrow.

Formulation associated to all trigonometric equations | Trigonometric Formulation

**1. sin²θ + cos²θ = 1**

• sin²θ = 1- cos²θ

• sinθ = √1-cos²θ

• cos²θ = 1- sin²θ

• cosθ = √1-sin²θ

**2. tan²θ+1 = sec²θ**

• secθ = √tan²θ+1

tan²θ = sec²θ – 1

tanθ = √sec²θ – 1

• sec²θ – tan²θ = 1

**3. 1+ cot²θ = cosec²θ**

cosecθ = √1+cot²θ

cot²θ = cosec²θ – 1

• cotθ = √cosec²θ – 1

• cosec²θ – cot²θ = 1
