It might be helpful to plot these points on a coordinate plan and then fill in the appropriate sinusoid. Amplitude Period Midline Find a possible formula for the trigonometric function whose values are in the above table. Note, you should choose to use either sin(x) or cos(x) as your parent function. f ( x ) = help (formulas) Use the above table, function or perhaps the graph you might have drawn to predict the following f(60) = f(-6) = f(90) = f (-42) = this
