4. the cosine function can be made to have the same values as the sine function for each angle by including a shifted in the calculation. a. amplitude b. wavelength c. period d. phase

Option D

phase

Step-by-step explanation:

By definition, the cosine function has the following form

Where is known as the phase angle

By definition the sinx function is equal to the cosx function with a phase shift of

So if we have the function

and we want to transform it into the function then

Finally

the answer is the option D

a

step-by-step explanation:

180

step-by-step explanation:

12-2=10

20-2=18

18x10=180
