Hi everyone,
I use STACK for teaching theory of groundwater flow, including governing equations. I do not quite understand the way how STACK displays derivatives of products. For example, if i want students to express the derivative of a*b with respect to x, i.e. noundiff(a*b,x,1), STACK will display in preview
rather than e.g.
which I think would be clearer to read. In more complicated expressions the readability can be really challenging. For example, -noundiff(-K*noundiff(H,x,1)*b,x,1) becomes
which is quite hard to interpret. Something like shown below would be easier.
Is there any way how the question author could configure STACK in how derivatives of products are shown in preview?
Thanks for help, best wishes,
Teemu
