At a specific point along a string the displacement of transverse wave can be described by the equation, y(t) = A sin(cot) where A = 0.85 m and 2.4 rad/s. A25% Part (a) Input an expression for the frequency. A 25% Part (b) What is the frequency in Hz? A 25% Part (c) What is the maximum y value the wave reaches in m? A 25% Part (d) Starting from = 0, what is the first time (in seconds) that the y value will be A/2?
