1Projection in a function space
An advanced study group compares two ways of approximating h(t)=t²by a polynomial a+bt on the interval[−1,1]. The exercise defines the inner product as the integral of f(t)g(t) over that interval and asks for the orthogonal projection onto the span of1and t.

A fictional analysis exercise studies f n(x)=nx/(1+n²x²)on[0,1]. The group first fixes x and examines the limit, then compares the result with a supremum-norm requirement.

A fictional numerical experiment solves y'=−20y with y(0)=1using explicit Euler. The exact solution decays, but one trial with step h=0.15alternates and grows in magnitude.

An ideal classical particle with charge q and mass m enters a spatially uniform constant magnetic field B. Its velocity has both parallel and perpendicular components, and no electric field, radiation loss, collision or relativistic correction is included in the supplied model.

A fictional shallow-foundation investigation finds three meters of soil above the water table and two meters below it at the point of interest. For this exercise the upper soil has total unit weight eighteen kilonewtons per cubic meter, the saturated lower soil has unit weight twenty kilonewtons per cubic meter, and water unit weight is ten kilonewtons per cubic meter.

A fictional simply supported beam has an eight-meter clear analytical span and carries a uniform total load of ten kilonewtons per meter. The exercise treats that load as already defined for the requested analysis, ignores support settlement and uses the elementary small-deflection beam idealization.
