ラジオ作りに心躍らせた昔のラジオ少年のように、 子供たちに、電子工作の道具ときっかけを届けたい

ロボットカーの組み立てとプログラミングを通して、
わーすごい!のワクワクを 
さあ、一緒にたのしもう!

With audio slideshows you can add recorded audio to whatever you want to deliver to your audience.

解説

このロボットカーは、自分たちで作ったスクラッチのプログラムからの指示を無線で受けて、黒線を辿ったり、障害物を検知したりしながらゴールに向かって走ることができます。

7. Mathmatics

7-1. TeX Macros

Here is a common vector space: \[L^2(\R) = \set{u : \R \to \R}{\int_\R |u|^2 < +\infty}\] used in functional analysis.

7-2. The Lorenz Equations

\[\begin{aligned} \dot{x} & = \sigma(y-x) \\ \dot{y} & = \rho x - y - xz \\ \dot{z} & = -\beta z + xy \end{aligned} \]

7-3. The Cauchy-Schwarz Inequality

\[ \left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right) \]

7-4. A Cross Product Formula

\[\mathbf{V}_1 \times \mathbf{V}_2 = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ \frac{\partial X}{\partial u} & \frac{\partial Y}{\partial u} & 0 \\ \frac{\partial X}{\partial v} & \frac{\partial Y}{\partial v} & 0 \end{vmatrix} \]

7-5. The probability of getting \(k\) heads when flipping \(n\) coins is

\[P(E) = {n \choose k} p^k (1-p)^{ n-k} \]

7-6. An Identity of Ramanujan

\[ \frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} = 1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}} {1+\frac{e^{-8\pi}} {1+\ldots} } } } \]

7-7. A Rogers-Ramanujan Identity

\[ 1 + \frac{q^2}{(1-q)}+\frac{q^6}{(1-q)(1-q^2)}+\cdots = \prod_{j=0}^{\infty}\frac{1}{(1-q^{5j+2})(1-q^{5j+3})}\]

7-8. Maxwell’s Equations

\[ \begin{aligned} \nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\ \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\ \nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\ \nabla \cdot \vec{\mathbf{B}} & = 0 \end{aligned} \]

7-9. TeX Macros

Here is a common vector space: \[L^2(\R) = \set{u : \R \to \R}{\int_\R |u|^2 < +\infty}\] used in functional analysis.
