Trignometric Graphs

Question 1

What are the quarters and starting point of a sine graph?

Answer 1

(0,0)

(90,1)
(180, 0)
(270, -1)
(360, 0)

Question 2

What are the quarters and starting point of a cosine graph?

Answer 2

(0,1)

(90,0)
(180, -1)
(270, 0)
(360, 1)

Question 3

What are the asymptotes, quarters and starting point of a tan graph?

Answer 3

(0,0)

90 is undefined, so is an asymptote.
(180,0)
270 is undefined, so is an asymptote.
(360,0)

Question 4

What are the periods of the three trigonometric graphs?

Answer 4

sine: 360°
cosine: 360°
tan: 180°

Question 5

What are the ranges of the y-axis (e.g: sin x) of the three trigonometric graphs?

Answer 5

sin x: -1 to 1
cos x: -1 to 1
tan x: any number
