What is the best linear approximation of the general function y = sin(ax) near x = 0? Homework Help ✎

Recall that a linear approximation is the equation of a secant line on a curvy function when you 'zoom in' on a given point until the graph appears to be linear. This is almost the same as a _________________________________________________.
