## MATHEMATICA TUTORIAL, Part 2.1: Eigenvalues

Use plain English or common mathematical syntax to enter your queries. To enter a matrix, separate elements with commas and rows with curly braces, brackets or parentheses.

## Differential Eigensystems: New in Wolfram Language 11

Use Shift-> μ to shift the eigenvalues by transforming the matrix to . This preserves the eigenvectors but changes the eigenvalues by -μ. The method compensates for the changed

## DEigensystem

Eigenvalues[] and its cognate functions are capable of returning the first few or last few eigencomponents by taking a second integer parameter. Eigenvalues[{matA, matB}, 3] for

Total lifesaver, i love how you can take a picture of a math problem and it will solve it for you, and it shows steps on how its solved and theres a lot of other cool features if you are thinking about downloading it u should try it. I only have a couple of complaints, like the fact that there's not an option to slide along a line or parabola and get the exact value of it at whatever x or y value on the graphs like Desmos.

I 100% recommend this. This app is blvery helpful for me in school and helping me get better at math, i don't know who the developers are, but I know they are geniuses. I'm in an advanced class and I feel that I've been falling behind, when I found this app by my friend it really helped me.
