Find the equation of a line tangent to the graph of f(x) = arcsin x at x =
. Homework Help ✎
Use the tangent line to find an approximate value of f(0.52).
Is your approximation an over or under estimate? Use the second derivative to justify your answer.
Because y = arcsin(0.52) is hard to evaluate, the tangent line at x = 0.52 will give a decent approximation of f(0.52).
and that will indicate if the tangent line is above or below the graph.
