# What is an example of a trigonometric equation?

## What is an example of a trigonometric equation?

A trigonometric equation is one that contains a trigonometric function with a variable. For example, sin x + 2 = 1 is an example of a trigonometric equation. The equations can be something as simple as this or more complex like sin2 x – 2 cos x – 2 = 0.

## What are the 3 trigonometric equations?

The three main functions in trigonometry are Sine, Cosine and Tangent….Sine, Cosine and Tangent.

Sine Function: sin(θ) = Opposite / Hypotenuse
Cosine Function: cos(θ) = Adjacent / Hypotenuse
Tangent Function: tan(θ) = Opposite / Adjacent

What is the ratio for Tangent OPP Adj Adj Opp Opp HYP HYP OPP?

ratio of hypotenuse to height: 10/6 = 5/3 = 1.666……

name ratio notation
sine opp/hyp sin(θ)

tangent opp/adj tan(θ)

What is the easiest way to solve Class 10 trigonometry?

Practice Questions From Class 10 Trigonometry Identities

1. Prove √(sec θ – 1)/(sec θ + 1) = cosec θ – cot θ
2. Prove (tan θ + sec θ – 1)/(tan θ – sec θ + 1) = (1 + sin θ)/cos θ
3. Prove sec θ√(1 – sin2 θ) = 1.
4. Given, √3 tan θ = 3 sin θ. Prove sin2 θ – cos2 θ = 1/3.
5. Evaluate cos2 θ tan2 θ + tan2 θ sin2 θ in terms of tan θ.

### How many trigonometric equations are there?

The six trigonometric functions are sine, cosine, secant, co-secant, tangent and co-tangent. By using a right-angled triangle as a reference, the trigonometric functions and identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse.

### Can Opp be bigger than adj?

The tangent is described with this ratio: opposite/adjacent. No restriction or rule on the respective sizes of these sides exists — the opposite side can be larger, or the adjacent side can be larger. So, the tangent ratio produces numbers that are very large, very small, and everything in between.

How do you calculate CAH?

CAH: Cos(θ) = Adjacent / Hypotenuse. TOA: Tan(θ) = Opposite / Adjacent.

What is the best way to learn trigonometry?

· The best way is to take courses. If you’re in high school, take Algebra 1 and 2, Trigonometry, Analytic Geometry, and/or Precalculus. If you’re in college take College Algebra, Trig, and then Calculus. 2) Or get the textbooks and teach yourself. Proving trigonometry functions is an art. There are often several ways to get to the answer.

#### What are the six trigonometry functions?

Trigonometric functions are functions related to an angle. There are six trigonometric functions: sine, cosine, tangent and their reciprocals cosecant, secant, and cotangent, respectively. Sine, cosine, and tangent are the most widely used trigonometric functions. Their reciprocals, though used, are less common in modern mathematics.

#### Is trigonometry considered high school or college level math?

Trigonometry is high school level math. Calculus is sometimes taken in high school, but is generally considered college level math. Algebra, trigonometry, and pre-calculus are more often taken in high school. They are however very important preparation for calculus.

How do you solve trigonometry?

If the given trig equation contains only one trig function,solve it as a basic trig equation.
