trig limits
Evaluate $\lim_{x\rightarrow 0} \frac{1-\cos4x}{x^2}$

so by the double angle

$\cos 4x = \cos^2 2x - \sin^2 2x$

this I understand but it shows it go further to $1-2\sin^2 2x$

This is where it starts to lose me.

so by the double angle

$\cos 4x = \cos^2 2x - \sin^2 2x$

this I understand but it shows it go further to $1-2\sin^2 2x$

This is where it starts to lose me.

$cos(2x) = cos^2(x) - sin^2(x) = 1 - 2sin^2(x) = 2cos^2(x) - 1$

You can find these by taking the cos^2 - sin^2 expression by applying $sin^2(x) + cos^2(x) = 1$

Re: trig limits
okay so

if $\cos^2 x = 1 - \sin^2 x$ true, then is $\cos^2 2x = 1 - \sin^2 2x$ true? That is the way my text book makes it seem

it skips over this step

$1 - \sin ^2 2x - \sin^2 2x$

then inputing that back in

I get

$\lim_{x\rightarrow 0} \frac{1- \cos 4x}{x^2} = \lim_{x \rightarrow 0} \frac{1 - (1 - \sin 2 sin^2\,\, 2x)}{x^2} \Rightarrow \lim_{x\rightarrow0} \frac{2 \sin^2 2x}{x^2}$

The work the book shows then gets a bit confusing from here (I am working on reviewing key trig components so please bear with me, the book is not always very clear.)

Since this is of the indeterminate form \displaystyle \begin{align*} \frac{0}{0} \end{align*}, L'Hospital's Rule can be applied.

\displaystyle \begin{align*} \lim_{x \to 0}\frac{1 - \cos{(4x)}}{x^2} &= \lim_{x \to 0}\frac{\frac{d}{dx}\left[ 1 - \cos{(4x)} \right] }{\frac{d}{dx} \left( x^2 \right) } \\ &= \lim_{x \to 0} \frac{ 4\sin{(4x)} }{ 2x} \\ &= \lim_{x \to 0} \frac{2\sin{(4x)}}{x} \end{align*}

This is again of the form \displaystyle \begin{align*} \frac{0}{0} \end{align*}, so we can use L'Hospital's Rule again...

\displaystyle \begin{align*} \lim_{ x \to 0 } \frac{2\sin{(4x)}}{x} &= \lim_{x \to 0} \frac{\frac{d}{dx} \left[ 2\sin{(4x)} \right] }{\frac{d}{dx}\left( x \right) } \\ &= \lim_{x \to 0} \frac{8\cos{(4x)}}{1} \\ &= \lim_{x \to 0} 8\cos{(4x)} \\ &= 8\cos{(4 \cdot 0 )} \\ &= 8\cdot 1 \\ &= 8 \end{align*}

Orthogonal trajectories of curves

Hello !
I have to find the orthogonal trajectories of the curves :

$$x^{2}-y^{2}=c , x^{2}+y^{2}+2cy=1$$ ..

How can I do this??

For this: $$x^{2}-y^{2}=c$$ I found $$\left | y \right |=\frac{M}{\left | x \right |}$$ ,and for this: $$x^{2}+y^{2}+2cy=1$$,I found: $$y=Ax-D$$,c,A,D $$\varepsilon \Re$$ .

Is this right??And how can I continue??

Hi evinda!

That is right enough.
Actually, you can sharpen the second one a bit since $D=c$.

What do you want to continue with?

What do you want to continue with?
Since both of the curves are given at the same subquestion,don't I have to find something common between those two solutions?? Or,what do I have to do??

The solution for the first set of curves is a set of hyperboles.
The solution for the second set of curves is a set of lines.
They have nothing in common.
So in my opinion they are separate questions and your answer is sufficient.

Hold on!

Something was still bugging me about that $c$ in the second set of curves $$x^2+y^2+2cy=1 \qquad (1)$$
When I started to draw them, I realized that
$$y=Ax-c \qquad \qquad (2)$$
is not the proper solution.
Draw them. You'll see!

Those lines are only orthogonal for points on 1 specific circle that is defined by $c$.
To find the curves that are orthogonal to the whole set of circles, we need to eliminate $c$.

From (1), we get that:
\begin{array}{}
\frac{x^2}{y}+y+2c&=&\frac 1 y \\
\frac{2x}{y}dx - \frac{x^2}{y^2}dy + dy + 0 &=& -\frac{1}{y^2}dy \\
2xydx&=&(x^2-y^2-1)dy
\end{array}
See, no $c$ involved anymore!
The solution of this differential equation is the set of curves (actually circles with their center on the y axis) in (1).

To find the orthogonal curves, we need to solve the "orthogonal" differential equation:
\begin{array}{}
(x^2-y^2-1)dx&=&-2xydy \\
\Big(1 - \frac{y^2}{x^2} - \frac 1 {x^2} \Big)dx &=& - \frac{2y}{x}dy \\
dx + \left(- \frac{y^2}{x^2}dx + \frac{2y}{x}dy \right) - \frac 1 {x^2}dx &=& 0 \\
x + \frac{y^2}{x} + \frac{1}{x} &=& 2C \\
x^2 + y^2 - 2Cx &=& -1 \\
(x - C)^2 + y^2 &=& C^2 - 1
\end{array}
In other words, this is a set of circles (with their center on the x-axis) instead of a set of lines.
