Applications of Second Order Equations-Springs Damped: Problem 1

(1 point)

(a) Using a trig identity, write y(t) = cos(4t) - 3 sin(4t) using only one cosine function.

y(t) = help (formulas)

(b) Using a trig identity, write y(t) = cos(4t) - 3 sin(4t) using only one cosine function.

y(t) = help (formulas)

(c) Using a trig identity, write y(t) = cos(4t) + 3 sin(4t) using only one cosine function in your answer.

y(t) = help (formulas)

(d) Using a trig identity, write y(t) = cos(4t) + 3 sin (4t) using only one cosine function in your answer.

y(t) = help (formulas)
