How to Solve a Trigonometry Equation by Factoring Quadratics

- Move the term on the right to the left by subtracting it from both sides. tan2 x – tan x = 0.
- Factor out tan x. tan x (tan x – 1) = 0.
- Set each of the two factors equal to 0. tan x = 0 or tan x – 1 = 0.
- Solve for the values of x that satisfy both equations.

**How do you factor trigonometric identities?**

When to Factor a Trigonometry Identity

- Factor sin x out of each term in the numerator.
- Replace the expression in the parentheses with its equivalent by using the Pythagorean identity.
- Now split up the fraction into a product of two fractions, carefully arranging the numerator and denominator.

**What is the easiest way to solve trigonometric identities?**

11 Tips to Conquer Trigonometry Proving

- Tip 1) Always Start from the More Complex Side.
- Tip 2) Express everything into Sine and Cosine.
- Tip 3) Combine Terms into a Single Fraction.
- Tip 4) Use Pythagorean Identities to transform between sin²x and cos²x.
- Tip 5) Know when to Apply Double Angle Formula (DAF)

### What are the 6 basic trigonometric functions?

There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

**Is Trig easier than algebra?**

Is Trig easier than algebra? Algebra 2/trig is a bit harder. But it is not that bad, as long as you keep up with your work DAILY. I found geometry easier than any of the other math courses in high school.

**What are the formulas in trigonometry?**

Basic Trigonometric Function Formulas

- sin θ = Opposite Side/Hypotenuse.
- cos θ = Adjacent Side/Hypotenuse.
- tan θ = Opposite Side/Adjacent Side.
- sec θ = Hypotenuse/Adjacent Side.
- cosec θ = Hypotenuse/Opposite Side.
- cot θ = Adjacent Side/Opposite Side.

## Which is an example of factoring a trig equation?

Factoring Trigonometric Equations Solving second degree trig functions can be accomplished by factoring polynomials into products of binomials. When factoring trigonometric equations, we can use the zero product property to set up two first degree trig equations that you can solve using the unit circle.

**How are trigonometric identities used to solve equations?**

The trigonometric identities act in a similar manner to multiple passports—there are many ways to represent the same trigonometric expression. Just as a spy will choose an Italian passport when traveling to Italy, we choose the identity that applies to the given scenario when solving a trigonometric equation.

**When to use zero product property in factoring trigonometric equations?**

When factoring trigonometric equations, we can use the zero product property to set up two first degree trig equations that you can solve using the unit circle. If an equation has sine and cosine, we substitute for one with an identity.

### How to solve a second degree trig equation?

Solving second degree trig functions can be accomplished by factoring polynomials into products of binomials. When factoring trigonometric equations, we can use the zero product property to set up two first degree trig equations that you can solve using the unit circle.
