What is a necessary component of a trigonometric equation?

• A polynomial of degree 3

• At least one trigonometric function

• A logarithmic function

• A quadratic term

Why are there infinite solutions to trigonometric equations?

• Because angles can be negative

• Because the unit circle allows for multiple rotations

• Because trigonometric functions are undefined

• Because angles are always positive

What should you check to determine if you need answers in radians or degrees?

• The color of the unit circle

• The size of the angle

• The directions provided in the problem

• The type of trigonometric function

What makes a trigonometric problem simple to solve?

• Using complex numbers

• Having multiple trigonometric functions

• Having only one trigonometric function

• Involving logarithmic functions

How can you find solutions for trigonometric equations with non-standard values?

• By using only the unit circle

• By guessing the values

• By ignoring the problem

• By using a calculator and inverse functions

What should you do if you encounter a secant in a trigonometric equation?

• Convert it to a tangent

• Use a logarithmic function

• Use the reciprocal function, cosine

• Ignore the secant

What is the first step in solving a trigonometric equation that requires algebraic manipulation?

• Isolate the trigonometric function

• Convert to a different function

• Use a calculator

• Guess the solution
