Question

Basic Math

f(x) = 10/cos-1(x). Use calculus to determine:

a) all critical values

b) any local extrema

c) any absolute extrema

d) the intervals where f is increasing/decreasing

e) any points of inflection rounded to the thousandths place

f) intervals where f is concave up/down

No interval was specified so I assumed 0

also I didn't get any concavity not sure if I'm right ornot.

I got x= pi as the critical value as well as the relative andabsolute minimum extrema.

would greatly appreciate some help
