Weblinearly independent or linearly dependent, we need to find out about the solution of If we find (by actually solving the resulting system or by any other technique) that only the trivial solution exists, then is linearly independent. However, if one or more of the 's is nonzero, then the set is linearly dependent. Example 12 WebOne more definition: Two functions y 1 and y 2 are said to be linearly independent if neither function is a constant multiple of the other. For example, the functions y 1 = x 3 and y 2 = 5 x 3 are not linearly independent (they’re linearly dependent), since y 2 is clearly a constant multiple of y 1. should you tip home repairmen https://thaxtedelectricalservices.com
