Consider the relation {{MATH_1}}. Implicitly differentiating with respect to {{MATH_2}}, we seem to obtain {{MATH_3}}. {{CMD_4}} {{CMD_5}}This is a valid use of implicit differentiation{{CMD_6}} {{CMD_7}}This is not a valid use of implicit differentiation{{CMD_8}} {{CMD_9}} Explain why or why not. Compare and contrast with the case of {{MATH_10}}. {{CMD_11}} {{CMD_12}}
