The discussion clarifies the difference between the differentiation notations d/dx and d/d(x^2). The notation d/dx represents the derivative with respect to the variable x, while d/d(x^2) indicates differentiation with respect to the variable x^2, treating x^2 as its own variable. This distinction is crucial for understanding how derivatives are calculated in different contexts, particularly in multivariable calculus.
PREREQUISITESStudents and educators in mathematics, particularly those focusing on calculus and differentiation techniques, as well as anyone looking to deepen their understanding of variable treatment in derivatives.
As far as I can see, the notation ##\frac {\partial}{\partial a^2}## means the partial (of something) with respect to ##a^2##, where ##a^2## is being treated as its own variable.Belgium 12 said:Hi members,
see attached PdF file.
What's the difference between d/dx and d/d(x^2) I don't understand this notation??
Thank You
