When our friends wrote {{MATH_61}}, what do they think the ``{{MATH_62}}'' represents? Are they correct? {{CMD_63}} Riley thinks that we can use the power rule on the {{MATH_64}}, which tells us that the students are using {{MATH_65}} as an exponent for the tangent function. However, in the case of inverse functions such as {{MATH_66}}, the {{MATH_67}} is not an exponent. {{CMD_68}} {{CMD_69}}
