Use linear regression techniques to find w and in the function, f(t) = sin(wt + 4) using the data below. t 0.0 0.1 0.2 0.91 0.5 0.92 0.6 0.83 f(t) 0.53 0.73 0.7 0.65 0.8 0.42 0.9 0.15 1.0 -0.1 1.1 -0.35 1.2 -0.58 1.3 1.4 1.7 1.8 1.9 -0.82 -0.91 -0.86 -0.76 -0.54 Note: there are an infinite number of solutions to the inverse sine function, sin¯¹(x) = ±y+nл where n € Z. You will have to utilize this definition to get your data in a linear form for fitting.
