Suppose we have two functions, {{MATH_108}}, and {{MATH_109}}, and we know that {{MATH_110}}, {{MATH_111}}, {{MATH_112}}, and {{MATH_113}}. What is the slope of the tangent line to the curve {{MATH_114}} at the point where {{MATH_115}}? {{CMD_116}} The slope of the tangent line to the curve {{MATH_117}} at {{MATH_118}} is given by {{MATH_119}}. By the QuotientRule and the Product Rule, this derivative is given by {{ENV_120}} {{CMD_121}} {{CMD_122}}
