Because Wen Shen is a Penn State employee, many of her lecture notes are available as open educational resources (OER). While the final published book may not be free, search for "Penn State Shen Numerical Analysis Notes." You will often find 80% of the content in PowerPoint or PDF format legally.
When functions are too complex to integrate or differentiate analytically, numerical calculus takes over. Topics include: an introduction to numerical computation wen shen pdf
How do you draw a smooth curve through random data points? Shen cheats data scientists’ tools: Because Wen Shen is a Penn State employee,
: Covers polynomial approximations, interpolation, numerical integration (Trapezoidal and Simpson’s rules), root-finding (Newton-Raphson, Bisection), and numerical methods for both Ordinary and Partial Differential Equations (ODEs and PDEs). Prerequisites Topics include: How do you draw a smooth
