If thewronskian w of f and g is 3e4t,and if f(t) = e2t,find g(t).
ehidna [41]
W(f(x),g(x))=\begin{vmatrix}f(x)&g(x)\\f'(x)&g'(x)\end{vmatrix}=f(x)g'(x)-g(x)f'(x)

We have f(t)=e^{2t}\implies f'(t)=2e^{2t}, so

W(f(t),g(t))=e^{2t}g'(t)-2e^{2t}g(t)=3e^{4t}
\implies e^{-2t}g'(t)-2e^{-2t}g(t)=3
\implies\dfrac{\mathrm d}{\mathrm dt}[e^{-2t}g(t)]=3
\implies e^{-2t}g(t)=\displaystyle\int3\,\mathrm dt
\implies e^{-2t}g(t)=3t+C
\implies g(t)=3te^{2t}+Ce^{2t}

where C is any arbitrary constant.

How do I solve this? Please show steps clearly so i can understand, thank you
Lesechka [4]

Answer:

The value of x=8.

Step-by-step explanation:

Given:

\frac{x+3}{x}-\frac{x+1}{x+4}=\frac{5}{x}

We need to solve this equation.

Solution:

First combining equation having same denominators we get;

\frac{x+3}{x}-\frac{5}{x}=\frac{x+1}{x+4}

Now denominators are common so we will solve the numerators we get;

\frac{x+3-5}{x}=\frac{x+1}{x+4}\\\\\frac{x-2}{x}=\frac{x+1}{x+4}

Now by cross multiplication we get;

(x-2)(x+4)=x(x+1)

Now Applying distributive property we get;

x^2+4x-2x-8=x^2+x\\\\x^2+2x-8=x^2+x

Now Combining the like terms we get;

x^2+2x-x^2-x=8\\\\x=8

Hence on solving we get the value of x=8.
