y = c1 cos(5x) + c2 sin(5x) is a two-parameter family of solutions of the second-order DE y'' + 25y = 0. If possible, find a sol
TEA [102]

Answer:

y = 2cos5x-9/5sin5x

Step-by-step explanation:

Given the solution to the differential equation y'' + 25y = 0 to be

y = c1 cos(5x) + c2 sin(5x). In order to find the solution to the differential equation given the boundary conditions y(0) = 1, y'(π) = 9, we need to first get the constant c1 and c2 and substitute the values back into the original solution.

According to the boundary condition y(0) = 2, it means when x = 0, y = 2

On substituting;

2 = c1cos(5(0)) + c2sin(5(0))

2 = c1cos0+c2sin0

2 = c1 + 0

c1 = 2

Substituting the other boundary condition y'(π) = 9, to do that we need to first get the first differential of y(x) i.e y'(x). Given

y(x) = c1cos5x + c2sin5x

y'(x) = -5c1sin5x + 5c2cos5x

If y'(π) = 9, this means when x = π, y'(x) = 9

On substituting;

9 = -5c1sin5π + 5c2cos5π

9 = -5c1(0) + 5c2(-1)

9 = 0-5c2

-5c2 = 9

c2 = -9/5

Substituting c1 = 2 and c2 = -9/5 into the solution to the general differential equation

y = c1 cos(5x) + c2 sin(5x) will give

y = 2cos5x-9/5sin5x

The final expression gives the required solution to the differential equation.

Answer:

1 : 80

Step-by-step explanation:

So you want to check Length of model : Length of real boat

50 cm : 40 m

But since the units don't match, make 40 m into 4000 cm

50 cm : 4000 cm

Divide both sides by 50 and you get

1 : 80

What is the slope- intercept equation of the line that passes through(0,2) and (6,6)?
Vsevolod [243]

Answer:

y = 2/3x +2

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

    = (6-2)/(6-0)

    =4/6

   =2/3

The slope intercept form of the equation for a line is

y= mx+b

y =2/3 x +b

We know the y intercept is 2  (the y intercept is when x=0)

y = 2/3x +2
