The function f(x) = sin(x) is not defined when x = X Using a calculator (and remembering that, if x ER, sin(x) means the sine of the angle whose radian measure is x), we construct a table of values correct to eight decimal places. sin(x) X X 1.0 0.84147098 0.5 0.95885108 0.4 0.97354586 0.3 0.98506736 0.2 0.99334665 0.1 0.99833417 0.05 0.99958339 0.01 0.99998333 0.005 0.99999583 0.001 0.99999983 sin(x) x-0 X From the table and the following graph we guess that lim sin x y= X
