Use MATLAB to compute all derivatives and check that the indicated function is the particular solution of the differential equation. x3 y´´´+2x2y´´+20xy´-78y=0 y= 20cos(5lnx)x-3(sen(5lnx)x
\( x^{3} y^{\prime \prime \prime}+2 x^{2} y^{\prime \prime}+20 x y^{\prime}-78 y=0 \) \( y=20 \frac{\cos (5 \ln x)}{x}-3 \frac{(\operatorname{sen}(5 \ln x)}{x} \) Comprobar que la función indicada es2 answers
