Evaluate your six trig functions given cotangent

The video tutorial explains how to evaluate trigonometric terms using triangles when a point is not on the unit circle. It covers the use of the Pythagorean theorem to find the sides of a triangle and calculates trigonometric ratios such as sine, cosine, and tangent. The tutorial also discusses the importance of rationalizing denominators in trigonometric expressions.

What is the cotangent of an angle in a right triangle?

• Adjacent over Opposite

• Opposite over Adjacent

• Hypotenuse over Adjacent

• Opposite over Hypotenuse

How do you find the hypotenuse of a right triangle if the other two sides are known?

• Subtract the smaller side from the larger side

• Multiply the two sides

• Add the squares of the two sides

• Use the Pythagorean theorem

What is the sine of an angle in a right triangle?

• Adjacent over Hypotenuse

• Adjacent over Opposite

• Hypotenuse over Opposite

• Opposite over Hypotenuse

What is the reciprocal of the sine function?

• Secant

• Cosecant

• Tangent

• Cotangent

Why is it important to rationalize the denominator in trigonometric expressions?

• To convert the expression to a fraction

• To simplify the expression

• To avoid having a square root in the denominator

• To make calculations easier
