Moreover, as {{MATH_42}} approaches {{MATH_43}}: {{CMD_44}} {{CMD_45}} The numerator is positive. {{CMD_46}} The denominator approaches zero and is positive. {{CMD_47}} Hence, the expression {{MATH_48}} will become arbitrarily large as {{MATH_49}} approaches {{MATH_50}}. We can see this in the graph of {{MATH_51}}. {{CMD_52}} {{ENV_53}} {{CMD_54}} {{CMD_55}} {{CMD_56}}
