Learn how to evaluate the six trig functions given an equation and constraint

The video tutorial explores the variability in drawing triangles based on given trigonometric information, focusing on cosine and cotangent functions. It discusses how different triangles can be drawn, the importance of constraints like cotangent negativity, and the role of reference angles. The tutorial also reviews homework assignments related to these concepts and provides a detailed analysis of cosine in different quadrants, concluding with final trigonometric calculations.

What is the main consideration when drawing different triangles based on cosine?

• The length of the hypotenuse

• The cosine of an angle

• The area of the triangle

• The perimeter of the triangle

In which quadrants is cotangent negative?

• First and third

• Second and fourth

• First and second

• Third and fourth

When determining the correct triangle to use, what is always positive?

• The hypotenuse

• The angle

• The opposite side

• The adjacent side

If cosine of Theta is positive, which direction should you move?

• Downwards

• To the left

• To the right

• Upwards

What is the value of tangent in the fourth quadrant?

• Positive

• Zero

• Negative

• Undefined
