I think is complementary but i'm not sure
The answer must be - cospi/2 which is not available in the option
Answer:
C.
Step-by-step explanation:
The pattern is the amount of sides each shape has.
Triangle - 3
Rectangle - 4
Pentagon - 5
Logically, the next shape would be a hexagon, a shape with 6 sides.
Answer:
y = 4 sin(t/2 + 4π/3) − 2
Step-by-step explanation:
General form:
y = a sin(2π/T t)
Given a = 4 and T = 4π:
y = 4 sin(2π/(4π) t)
y = 4 sin(t/2)
Add horizontal shift of -4π/3 and vertical shift of -2:
y = 4 sin(t/2 − (-4π/3)) − 2
y = 4 sin(t/2 + 4π/3) − 2
