However, we can linearize this relation by plotting R vs sin(20), in other words, if you call y = R and x = sin(20), the range equation adopts a straight line equation of the form y = a.x. Use Excel (or any other package of your choice) to plot sin(20) vs. R and fit the data points to a straight line. Compare the slope obtained from fitted results to its real value predicted by the range equation
