Learn how to evalute the six trig functions given a trig ratio

The video tutorial explains how to evaluate the six trigonometric functions for a given angle using cotangent. It begins with an introduction to cotangent and its reciprocal relationship with tangent. The instructor then demonstrates how to create a triangle and find the hypotenuse using the Pythagorean theorem. The tutorial proceeds to calculate the six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent, highlighting their reciprocal relationships. Finally, the video covers rationalizing denominators and simplifying radicals in trigonometric expressions.

Which theorem is used to find the hypotenuse in a right triangle?

• Pythagorean theorem

• Binomial theorem

• Remainder theorem

• Fundamental theorem of calculus

What is the simplified form of the square root of 130?

• 10

• 11

• sqrt(130)

• 13

Which trigonometric function is the reciprocal of sine?

• Cosine

• Secant

• Cosecant

• Tangent

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