How to manipulate 2D plots? https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=7142
When it comes to visual analysis, large datasets or data with intricate internal details often makes plotting in 2D useless, as the outcome is either just a fraction of the full dataset, or no details ... [plotting] [graphics] [dynamic] [gui-construction]

I am wondering how to implement the multi-peak detecting and fitting in Mathematica. Following is an example of fitting the data using three peaks (such that the data ~ peak1 + peak2 + peak3). The ... [fitting] [data] [peak-detection]

The basic multivariable Taylor expansion formula around a point is as follows: $$ f(\mathbf r + \mathbf a) = f(\mathbf r) + (\mathbf a \cdot \nabla )f(\mathbf r) + \frac{1}{2!}(\mathbf a \cdot \nabla)... [calculus-and-analysis] [series-expansion]
