For a sine function with amplitude = 0.75 and period = 10, what is y (4) ?

The general formula for sine function is y (x) = A sin (2πx/t). Here, x = displacement = 4, time period, t = 10 and Amplitude, A = 0.75, then, y (4) = 0.75 sin (2π*4/10) = 0.75*0.04 = 0.03. Thus, the value of y (4) wll be 0.03
