Question

The period of cos 5 is​

Answer 1

For any general cosine function of the form

f

(

t

)

=

A

cos

B

t

, the amplitude is

A

and represents the maximum displacement from the t-axis, and the period is

T

=

2

π

B

and represents the number of units on the

t

axis for a complete cycle or wavelength of the graph to pass by.

So in this particular case, the amplitude is

1

, and the period is

T

=

2

π

5

=

72

∘

,

since by the conversion factor,

360

∘

=

2

π

r

a

d

.
