Why is it important to have all terms in the same trigonometric function when factoring?

• It is required by mathematical rules.

• It makes the expression longer.

• It simplifies the factoring process.

• It changes the value of the expression.

What is one over cotangent equivalent to?

• Tangent

• Secant

• Cosine

• Sine

What happens when you multiply sine by cosecant?

• The result is zero.

• The result is one.

• The result is sine squared.

• The result is cosecant squared.

What is the factored form of 4X^2 - 4X + 1?
