How to evaluate for the secant of an angle without using a calculator

The video tutorial covers the concept of secant of π/3, emphasizing the importance of understanding trigonometric functions without relying on calculators. It explains the relationships in 30-60-90 triangles and how these can be used to find exact trigonometric values. The tutorial also highlights the proportionality of special right triangles and concludes with a Q&A session to address student queries.

What is the secant of π/3 equivalent to in degrees?

• 45 degrees

• 60 degrees

• 30 degrees

• 90 degrees

Which of the following is a property of a 30-60-90 triangle?

• The hypotenuse is equal to the long leg.

• The long leg is equal to the short leg.

• The hypotenuse is twice the length of the short leg.

• The short leg is twice the length of the hypotenuse.

In a 30-60-90 triangle, if the short leg is 7, what is the length of the hypotenuse?

• 7

• 14√3

• 14

• 7√3

How do you calculate the secant of an angle using a right triangle?

• Hypotenuse over opposite

• Hypotenuse over adjacent

• Adjacent over hypotenuse

• Opposite over hypotenuse

What is the secant of 60 degrees in a 30-60-90 triangle?

• 1/2

• 2

• 1

• √3
