Show linear independence in p6 f
WebApr 23, 2012 · To prove that 1, sin (x), and cos (x) are independent, you want to prove that the only way you can have for all x is to have . But that is what we want to prove- we cannot assume it. Since that is true for all x, it is, in particular, true for x= 0, we must have. And, for , we must have. Finally, for , we must have. WebFeb 13, 2024 · In order to prove that we show the functions x i: F → F are linearly independent. Consider a linear combination of the functions x i: f ( x) = ∑ i = 0 n a i x i = 0. …

WebLinear independence—example 4 Example Let X = fsin x; cos xg ‰ F. Is X linearly dependent or linearly independent? Suppose that s sin x + t cos x = 0. Notice that this equation holds for all x 2 R, so x = 0 : s ¢ 0+ t ¢ 1 = 0 x = … 2: s ¢ 1+ t ¢ 0 = 0 Therefore, we must have s = 0 = t. Hence, fsin x; cos xg is linearly independent. What happens if we tweak this example by a … WebLinearly independent functions De nition The set of functions f 1;:::; ng is called linearly independent on [ a ; b ] if c1 1(x )+ c2 2(x )+ + cn n(x ) = 0 ; for all x 2 [a ; b ] implies that c1= c2= = cn= 0. Otherwise the set of functions is called linearly dependent .
