(Roll the mouse over the area above to see the corrections in blue) Explanations
The presence of parameters, or arbitrary constants, like w and L, seem to give students all kinds of trouble in calculus (or any prior class). The correct approach is to treat these constants as numbers whose values happen not to be specified. The constant multiple rule should then be used to pull these constants out in front of any expression that is to be differentiated. |
