Question

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

Answer 1

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
