Concept explainers
The sine
is important in electrical engineering. [The integrand f(t) = (sin t)/t is not defined when t = 0, but we know that its limit is 1 when t → 0, So we define f(0) = 1 and this makes f a continuous function everywhere.]
- (a) Draw the graph of Si.
- (b) At what values of x does this function have
local maximum values? - (c) Find the coordinates of the first inflection point to the right of the origin.
