Question
The continuous extension of (sin x)^x [0,π]
a) Graph f(x)= (sin x)^x on the interval 0 ≤ x ≤ π. What value would you assign to f(x) to make it continuous at x = 0?
b) Verify your conclusion in part (a) by finding limx→0+ f(x) with L’Hôpital’s Rule.
c) Returning to the graph, estimate the maximum value of f(x) on [0, π].
About where is max f(x) taken on?
d) Sharpen your estimate in part (c) by graphing ƒ in the same window to see where its graph crosses the x-axis. To simplify your work, you might want to delete the exponential factor from the expression for f' and graph just the factor that has a zero.
