Evaluate the six trig functions using a right triangle and secant of theta

The video tutorial covers the basics of right triangles, including the definitions of sine, cosine, and tangent. It explains the reciprocal trigonometric functions: secant, cosecant, and cotangent. The tutorial demonstrates how to use these functions to solve problems, including using the Pythagorean theorem to find missing sides of a triangle. It also covers evaluating and rationalizing trigonometric functions, providing multiple methods for understanding and applying these concepts.

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

• Adjacent over hypotenuse

• Opposite over hypotenuse

• Adjacent over opposite

• Hypotenuse over opposite

Which trigonometric function is the reciprocal of cosine?

• Cosecant

• Sine

• Tangent

• Secant

If secant of an angle is 2, what is the cosine of that angle?

• 1/2

• 1/3

• 1

• 2

How do you find the third side of a right triangle if two sides are known?

• Use the Pythagorean theorem

• Use the cosine function

• Use the sine function

• Use the tangent function

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

• Opposite over adjacent

• Adjacent over hypotenuse

• Hypotenuse over opposite

• Adjacent over opposite

What is the cosecant of an angle if the sine is 1/2?

• 2

• 1/2

• 3

• 1

Which trigonometric function is the reciprocal of tangent?
