You can find a coterminal angle by adding two full turns to an angle.

An angle that is zero is coterminal with any multiple of a full turn.

The unit circle has a radius of 1.

Adding one full turn to an angle gives a coterminal angle.

A function can have more than one y-intercept.

All coterminal angles point to the same spot on the circle.

Coterminal angles end at the same position on a circle.

A logarithmic function can have a negative argument.

The horizontal asymptote of the function y=3x22x2y = \frac{3x^2}{2x^2}y=2x23x2​ is y=32y = \frac{3}{2}y=23​.

The cosine of an angle in the second quadrant is always positive.

Coterminal angles can have different sizes but still point in the same direction.

Coterminal angles can be positive or negative.

Logarithms and exponential functions are inverses of each other.

Polynomial functions always have at least one real root.

To check if two angles are coterminal, subtract them and see if the result is a multiple of a full turn.

A coterminal angle is always smaller than the original angle.

You cannot subtract a full turn from an angle to find a coterminal angle.

Coterminal angles always have the same sine and cosine values.

For an angle measured in radians, adding 2π2\pi2π gives a coterminal angle.

Two angles are coterminal if they overlap when drawn in standard position.

Any two angles that are coterminal will have the same sine and cosine values.

Only positive angles can have coterminal angles.

Negative angles cannot be coterminal with positive angles.

Coterminal angles must always be positive.

The tangent function is undefined at 90∘90^\circ90∘ and 270∘270^\circ270∘.

The concept of coterminal angles applies only to angles measured in degrees.

Adding a fraction of a turn to an angle will not result in a coterminal angle.

You can find a coterminal angle by adding or subtracting a full turn of a circle.

Coterminal angles are used in trigonometry and geometry.

A parabola with a positive leading coefficient opens downward.

An angle of zero cannot have coterminal angles.

Coterminal angles are helpful in solving periodic problems.

The graph of y=∣x∣y = |x|y=∣x∣ is symmetric about the y-axis.

The sine function is even.

Adding or subtracting 360∘360^\circ360∘ to an angle always gives a coterminal angle.

If two angles are coterminal, they look the same on a unit circle.

The domain of a rational function excludes values that make the denominator zero.

Coterminal angles share the same initial and terminal sides.

The end behavior of a polynomial function is determined by its leading term.
