Find the following when a = -1, b = 2, c = -1/4<br> (4b - 3)/(2a) -1
Katena32 [7]
We substitute the given into the equation
given: a=-1, b=2, c=\frac{-1}{4}
=(\frac{4b-3}{2a}-1
=\frac{4(2)-3}{2(-1)}-1
=\frac{8-3}{-2}-1
=\frac{5}{-2}-1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:
\frac{5}{-2}=-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
=\frac{5}{-2}\frac{-1}{1}×\frac{-2}{-2}         (denominator should be -2=common)
=\frac{5}{-2}+\frac{2}{-2}
=\frac{7}{-2}
which also = to -3.5

Consider the initial value problem y′′+36y=2cos(6t),y(0)=0,y′(0)=0. y″+36y=2cos⁡(6t),y(0)=0,y′(0)=0. Take the Laplace transform
Bingel [31]

Recall the Laplace transform of a second-order derivative,

L(y''(t)) = s^2Y(s)-sy(0)-y'(0)

and the transform of cosine,

L(\cos(at))=\dfrac s{a^2+s^2}

Here, both y(0)=y'(0)=0, so taking the transform of both sides of

y''(t)+36y(t)=2\cos(6t)

gives

s^2Y(s)+36Y(s)=\dfrac{2s}{36+s^2}

\implies Y(s)=\dfrac{2s}{(s^2+36)^2}
