Verify that the functions: cos(ln x), sin(ln x), form a fundamental set of solutions of the DE x^2y"+xy'+y=0 on the interval (0,infinity).Form the general solution.

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

sine

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
