SUMMARY

The discussion centers on the steps required for function orthogonalization in Exercise 8, which involves the properties of functions phi 1 and phi 2. Participants express confusion regarding the definitions of variables u1, u2, and alpha, as these are not clearly provided in the problem statement. The hint suggests following previous exercises, yet many students report difficulty in applying this guidance effectively. The lack of clarity in variable definitions hinders progress in solving the exercise.

PREREQUISITES
  • Understanding of function orthogonalization principles
  • Familiarity with linear algebra concepts, particularly inner products
  • Knowledge of the properties of orthogonal functions
  • Experience with mathematical notation and problem-solving strategies
NEXT STEPS
  • Review the definitions and properties of orthogonal functions in linear algebra
  • Study the process of function orthogonalization through examples
  • Examine previous exercises related to the topic for clearer methodologies
  • Explore resources on inner product spaces and their applications
USEFUL FOR

Students studying linear algebra, particularly those tackling function orthogonalization problems, and educators seeking to clarify concepts related to inner products and orthogonal functions.

Homework Statement



The problem is Exercise 8

[PLAIN]http://postimage.org/image/6kpizm8dj/ [/PLAIN]

Homework Equations



in picture

The hint says "follow the steps as in the previous exercise, using the properties of (phi 1) and (phi 2) as already established".

The Attempt at a Solution



I tried substituting in phi 1 and phi 2 to solve for beta and gamma but that didn't work.

talked to 5 people in my class who also don't know what to do and online is of no help :(
 
What you show defines phi1 and phi2 in terms of u1 and u2 but does not say what u1 and u2 are. Also #7 asks you to "Show that [itex]\alpha= -(\phi_1, u_2)[/itex]" but you give no definition of [itex]\alpha[/itex].
