Cad Constant Error

AI Thread Summary

The user encountered a constant error while trying to graph the function f(x)=X^3-9X in MathCAD, specifically related to the variable 9X. A suggestion was made to use the format 9*x instead, which did not resolve the issue. Ultimately, the user found success by using the format x*9 for the coefficient. This indicates that the order of multiplication can affect the function's graphing in MathCAD. Proper syntax is crucial for successful graphing in the software.

I don't have mathcad, but based on what you've typed here, I'm guessing it should be 9*x.

Ok, I figured it out by playing around with the coeffiecient. It's x*9. 9*x did not work.

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
