Question

Amplitude of 5 + 2 i​

Answer 1

Answer:

Please follow me then I will tell you the answer

Answer 2

Answer:

Use the form a⋅cos(bx−c)+d

Given equation is y=(52)cos(x2)

In this equation 

a=52,b=12,c=0,d=0

Amplitude = a=52

Period =2πb=2π12=4π

Phase shift = c/b = 9

Vertical shift = d = 0

-10, 10, -5, 5]}
