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.
158 words, under 1 min2A moving peak and uniform error
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.
171 words, under 1 min3An explicit numerical stability check
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.
