Graphic Trigonometric Functions (5.1.2)

Question 1

What can angles be measured in, and which measurement is the best for calculus?

Answer 1

• Angles can be measured in degrees or radians. When using calculus, it is best to work with radian measure.

Question 2

How do you convert from radians to degrees and from degrees to radians?

Answer 2

• To convert from degrees to radians, multiply by π/180. To convert from radians to degrees, multiply by 180/π

Question 3

• The graphs of the trigonometric functions are periodic. Use the sine and cosine curves to extrapolate the graphs of tangent, secant, cosecant, and cotangent.

Answer 3

• The graphs of the trigonometric functions are periodic. Use the sine and cosine curves to extrapolate the graphs of tangent, secant, cosecant, and cotangent.
