Webf (x)=Asinx+Bcosx,for some non−zero constants A and B,f (x)=Asinx+Bcosx,for some non−zero constants A and B, defined on ]0,2π []0,2π [, which of the following (s) is (are) true? Notice that The given function may be expressed as A2+B2−−−−−−−√sin (x+α),A2+B2sin (x+α), where α∈ [0,π]α∈ [0,π] such that … WebNow to prove that $\sin(x)$ and $\cos(x)$ are linearly independent, you would compute the determinant of the Wronskian matrix, which then you get $\det(W) = -1 \neq 0$. So $\sin(x)$ and $\cos(x)$ are linearly independent thus { $\sin(x),\cos(x)$ } is a basis.

WebWhat is the full form of asin? - Arcsine - Arcsine (asin or arc-sine or inverse sine) is the inverse of the sine function. WebSo for instance, to show commutativity you would take two functions of that form, say f(x) = asinx + bcosx and g(x) = csinx + dcosx, and show that f + g = g + f (i.e. that (asinx + bcosx) + (csinx + dcosx) = (csinx + dcosx) + (asinx + bcosx) for all x in R). But those axioms are going to be true for these specific kinds of functions because ...
