Estimate the total area between f(x)=cos(x^3) and the x-axis for 0≤ x ≤ π^1/3. (You will want to use a calculator or such to get a reasonably accurate estimate.)
Looking at the graph, the area they want is the sum of the blue and pink areas, which will require integrating each one separately and taking absolute values. It looks like technology is the way to go; are they perhaps expecting a numerical integration on a calculator?
Ah, I missed that they're looking for the total area and not simply an approximation for the definite integral. In that case, W|A returns an approximation of:
