Family of methods known as "Methods of weighted residuals". Example: cantilevered beam with distributed load. ![](attachments/Pasted%20image%2020221117123410.png#invert) The governing equation is differential. Assume an approximation using a linear combination of displacements. Tilda shows an approximation. ![](attachments/Pasted%20image%2020221117123518.png#invert) R is an error - we would like to drive it to zero. That can only happen when we have the solution!
