Find the two horizontal and two vertical tangent lines of the equation x^2+xy+y^2=9.

valina [46]

Differentiating w.r.t y,
We get,

<span>2 x (d x/d y) + y (d x/d y) + x + 2 y = 0 </span>

<span>Put
d x/d y = 0 </span>

The equation becomes:
<span>x=2 y </span>

<span>substituting into main equation

We, get

3 y^2 =9 </span>

y= √3

x = <span>± 2√3</span>

A curve is described by the following parametric equations: <br> x = 4-t<br> y = t^2 -2

marta [7]

Answer:

Step-by-step explanation:

Given

$x=4-t$

and $y=t^2-2\quad \ldots(i)$

So, $t=4-x$

Substitute the value of $t$ in $(i)$

$y=(4-x)^2-2$

$y+2=(4-x)^2$

So it represent a parabola shown in the figure
