Solve the equation. dy dx = ay + b cy + d , where a, b, c, and d are constants. (assume a ≠ 0 and ay + b ≠ 0.)

Reil [10]

It solves it in x. the solution for y includes heavy use of the product log function.

dy/dx = ay + b/cy +d

(cy +d/ ay + b) dy = dx

∫ (cy +d/ ay + b) dy = x (t) + C

Into solving the integral, integration by parts followed by u substitution and another integration by parts.

∫ (cy +d/ ay + b) dy

u = cy + d dv = dy/ay + b

du = c dy v = ln I ay + b l / a

Then, use u substitution for the new integral

u = ay + b

du = a dy

∫ ln l ay + b I dy = ∫ ln IuI /a du = 1/a ∫ ln luI du

Integrating the natural log includes thus far another integration by parts

r = ln IuI ds = du

dr = du / u (s) = du

∫ ln IuI / du = u ln IuI - ∫ du = u ln IuI - ∫ a dy = (ay + b) ln Iay +bl – ay

The original integral of expression

∫ (cy +d/ ay + b) dy = cy + d/a ln lay+bl – c/a² [(ay+b) ln lay+bl – ay]

Then simplify

∫ (cy +d/ ay + b) dy = cy + d/a ln lay+bl – c/a²[(ay+b) ln lay+bl – ay]

= a (cy + d)/a² ln lay+bl – c (ay+b)/ a²ln lay+bl + c/a² ay

= cay + ad – cay – cb/ a² ln lay+bl + cay/a²

= ad – cb/a²ln lay+bl + cy/a

The final answer will be

x(t) + C = ad – cb/a² ln lay+bl + cy/a

x(t) = ad – cb/a² ln lay+bl + cy/a + k

vodka [1.7K]

Answer:

Terrance is incorect.

Correct output coordinates (-y,-x)

Step-by-step explanation:

Let $(x,y)$ be the input coordinates.

First translation is a rotation of 180° clockwise about the origin. This translation has a rule

$(x,y)\rightarrow (-x,-y)$

Second translation is a reflection over the line y = x. The general rule for the reflection across the line y=x has the rule

$(a,b)\rightarrow (b,a)$

When a sequence of two translations are applied to the initial input coordinates, then

$(x,y)\rightarrow (-x,-y)\rightarrow (-y,-x)$

As you can see Terrance made a mistake and these two transformations do not cancel themselves out.
