<em>Here</em><em>, </em>

<em> </em>

<em>Triangle</em><em> </em><em>A</em><em>D</em><em>C</em><em> </em><em>and</em><em> </em><em>triangle</em><em> </em><em>ABD</em><em> </em><em>are</em><em> </em><em>similar</em><em> </em><em>triangle</em><em> </em><em>as</em><em> </em><em>they</em><em> </em><em>are</em><em> </em><em>similar</em><em> </em><em>by</em><em> </em><em>A.A.A</em><em> </em><em>axiom</em><em>.</em>

<em>now</em><em>,</em><em> </em><em>as</em><em> </em><em>they</em><em> </em><em>are</em><em> </em><em>similar </em><em> </em><em>their</em><em> </em><em>sides</em><em> </em><em>are</em><em> </em><em>proportional</em><em> </em><em>to</em><em> </em><em>eachother</em><em>, </em>

<em>CD</em><em>/</em><em>BD</em><em> </em><em>:</em><em> </em><em>AB</em><em>/</em><em>AC</em><em> </em><em>:</em><em> </em><em>AD</em><em>/</em><em>AD</em>

<em>4</em><em>.</em><em>3</em><em>/</em><em>4</em><em> </em><em>:</em><em> </em><em>AB</em><em>/</em><em>5</em><em>.</em><em>6</em><em> </em><em>:</em><em> </em><em>AD</em><em>/</em><em>AD</em><em>.</em>

<em>Taking</em><em> </em><em>1</em><em>st</em><em> </em><em>and</em><em> </em><em>srcond</em><em> </em><em>ratios</em><em> </em><em>we</em><em> </em><em>get</em><em>,</em>

<em>4</em><em>.</em><em>3</em><em>/</em><em>4</em><em>=</em><em>AB</em><em>/</em><em>5</em><em>.</em><em>6</em>

<em>or</em><em>,</em><em> </em><em>4AB</em><em> </em><em>=</em><em> </em><em>5</em><em>.</em><em>6</em><em>×</em><em>4</em><em>.</em><em>3</em><em> </em><em> </em><em> </em><em>(</em><em>cross</em><em> </em><em>multiplication</em><em>)</em>

Initial value problems dy/dx+2y=3. Y(0)=1
Pavel [41]

The initial value equation is y = \frac 12(3 - e^{-2x})

<h3>How to solve the initial value?</h3>

The equation is given as:

\frac{dy}{dx} +2y = 3

Where

Y(0) = 1

Subtract 2y from both sides in the equation

\frac{dy}{dx}  = -2y + 3

Rewrite as:

\frac{dy}{-2y + 3}  =  dx

Integrate both sides of the equation

-\frac 12\ln|-2y + 3| = x + C_o

Multiply through by -2

\ln|-2y + 3| = -2x + C_1

Take the exponent of both sides

-2y + 3 = Ce^{-2x

Next, we solve for C under the initial condition Y(0) = 1.

This gives

-2(1) + 3 = Ce^{-2 * 0

Evaluate

-2 + 3 = C

Solve for C

C = 1

Substitute C = 1 in -2y + 3 = Ce^{-2x

-2y + 3 = e^{-2x

Next, we solve for y

y = \frac 12(3 - e^{-2x})

Hence, the initial value equation is y = \frac 12(3 - e^{-2x})
