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
