2. Find the solution of each differential equation. (a) y/2y-8y = 0 (b) 25y/- 20y + 4y = 0 (c) y + 2y + 2y = 0 2. Find the solut
jek_recluse [69]

Each of these ODEs is linear and homogeneous with constant coefficients, so we only need to find the roots to their respective characteristic equations.

(a) The characteristic equation for

y'' - 2y' - 8y = 0

is

r^2 - 2r - 8 = (r - 4) (r + 2) = 0

which arises from the ansatz y = e^{rx}.

The characteristic roots are r=4 and r=-2. Then the general solution is

\boxed{y = C_1 e^{4x} + C_2 e^{-2x}}

where C_1,C_2 are arbitrary constants.

(b) The characteristic equation here is

25r^2 - 20r + 4 = (5r - 2)^2 = 0

with a root at r=\frac25 of multiplicity 2. Then the general solution is

\boxed{y = C_1 e^{2/5\,x} + C_2 x e^{2/5\,x}}

(c) The characteristic equation is

r^2 + 2r + 2 = (r + 1)^2 + 1 = 0

with roots at r = -1 \pm i, where i=\sqrt{-1}. Then the general solution is

y = C_1 e^{(-1+i)x} + C_2 e^{(-1-i)x}

Recall Euler's identity,

e^{ix} = \cos(x) + i \sin(x)

Then we can rewrite the solution as

y = C_1 e^{-x} (\cos(x) + i \sin(x)) + C_2 e^{-x} (\cos(x) - i \sin(x))

or even more simply as

\boxed{y = C_1 e^{-x} \cos(x) + C_2 e^{-x} \sin(x)}

Paghambingin ang mito, alamat, at kuwentong-bayan na iyong binasa ayon sa mga elemento ng bawat isa gamit ang Venn Diagram. Gawi
Rzqust [24]

Answer:

. Ang alamat ay isang uri ng alamat na binubuo ng isang salaysay na nagtatampok ng mga pagkilos ng tao na napansin o pinaniwala kapwa ng nagsasabi at nakikinig na naganap sa loob ng kasaysayan ng tao. Ang mga salaysay sa ganitong uri ay maaaring magpakita ng mga pagpapahalaga sa tao, at nagtataglay ng ilang mga katangian na nagbibigay ng katotohanan sa katotohanan

2.Ang kuwentong bayan ay isang nagpapahiwatig na katawan ng kultura na ibinahagi ng isang partikular na pangkat ng mga tao; sumasaklaw ito ng mga tradisyon na karaniwan sa kultura, subkulturang iyon o pangkat. Kasama rito ang mga tradisyon na oral tulad ng mga kwento, salawikain at biro

3.Ang alamat ay isang katutubong alamat na binubuo ng mga salaysay na may pangunahing papel sa isang lipunan, tulad ng mga kwentong pang-foundational o mitolohiya ng pinagmulan. Ang mga pangunahing tauhan sa mga alamat ay karaniwang mga diyos, demigod, o higit sa likas na tao.
