Unformatted text preview: Math 2025 Quiz #3 (Fall 2004) Name: Inner product on functions on [0,, b] (piecwise continuous, continous, etc.) is given by (f, g) : fab fltlgﬁ) dt. The norm is "m b Hm=¢mnz fmet If A is a subset. of R” then the indicator function of A is the function XA : R“ -> R” given by 1 ifteA “(75) z {o ifteé/l In the following we will always use a = 0 and b : 1. A) Evaluate the following inner products: a ‘ W ‘ W(W“L%ﬂﬂﬂh= i Lim-zilmfl (2) Let f(t) = t2 and g(z€) : t + 1.
