Find the value of the trigonometric expression using inverse

The video tutorial explains how to find the inverse tangent of a point not on the unit circle by creating a triangle. It discusses the constraints of the inverse tangent function and applies the Pythagorean theorem to find the hypotenuse. The lesson concludes with finding the secant as the reciprocal of cosine.

What is the first step when given a point not on the unit circle to find its inverse tangent?

• Ignore the point

• Convert it to a sine function

• Create a triangle

• Use the unit circle directly

Why can only one triangle be used when finding the inverse tangent?

• Because the unit circle is not applicable

• Because of the constraints of the inverse tangent function

• Because there are no other triangles

• Because it is a positive tangent

What is the Pythagorean theorem used for in this context?

• To find the adjacent side of the triangle

• To find the angle of the triangle

• To find the hypotenuse of the triangle

• To find the opposite side of the triangle

What is the secant of an angle defined as?

• The reciprocal of sine

• The reciprocal of cosine

• The reciprocal of tangent

• The reciprocal of cotangent

How is secant calculated in this problem?

• Opposite over hypotenuse

• Hypotenuse over opposite

• Adjacent over hypotenuse

• Hypotenuse over adjacent
