Master evaluating the six trig functions when given an equation and constraint

The video tutorial explains how to evaluate the six trigonometric functions when given an equation and a constraint on the triangle's quadrant. It covers identifying the correct quadrant for triangle placement, calculating sine, cosine, and tangent ratios, and using the Pythagorean theorem to find side lengths. The tutorial also demonstrates finding reciprocal trigonometric functions and solving example problems in different quadrants.

What is the first step in evaluating trigonometric functions with constraints?

• Identify the hypotenuse length

• Calculate the sine of the angle

• Find the reciprocal functions

• Determine the correct quadrant for the triangle

Why is it important to consider the sign of the adjacent side when constructing right triangles?

• It determines the length of the hypotenuse

• It affects the angle measurement

• It changes the type of triangle

• It ensures the triangle is in the correct quadrant

In the third quadrant, what is the sign of the y-value for a right triangle?

• Negative

• Zero

• Undefined

• Positive

How do you calculate the tangent of an angle in a right triangle?

• Adjacent over hypotenuse

• Opposite over adjacent

• Hypotenuse over opposite

• Adjacent over opposite

What is the cosine of an angle in the second quadrant if the adjacent side is negative?

• Undefined

• Positive

• Negative

• Zero

Which trigonometric function is the reciprocal of sine?

• Cosine

• Cotangent

• Secant

• Cosecant

What is the importance of constraints when evaluating trigonometric functions?

• They change the length of the sides

• They ensure the correct sign of the function values

• They affect the calculation of angles

• They determine the type of triangle
