Step-by-step explanation:
Answer: ¢=68.2
Step-by-step explanation:
y(t) = 2sin4πt + 5cos4πt
Let , x = Asin¢ = 5
y = Acos¢ = 2
A = sqrt(5²+2²)
A= 5.39
y(t) = Acos¢sin4πt + Asin¢cos4πt
From Trigonometry rule,
y(t)= Asin(wt +¢)
tan¢ = 5/2
¢ = arctan(5/2) = 68.2°
y(t) = 5.39sin(wt + 68.2)
Where w = 4π
The angle ¢= 68.2°
