Interactive: Dynamic Figure 2.5.2
The dynamic figure shows the graph of the secant function and the graph of the tangent function for 0<=x<=π. Use the slider to explore tan(x), sec(x), and the ratio (tan(x))/(sec(x)) both graphically and numerically for different values of x.
Which of the following limits does not exist?
None of the limits exist.
All three limits exist.
lim(x->(π)/(2)^(+))sec(x)
lim(x->(π)/(2)^(-))sec(x)
lim(x->(π)/(2)^(-))sec(x)
