Given a right triangle \(ABC\) (see the picture). Find the
valid relation between the angle \(\alpha \)
and the sides of the triangle.
\(\mathop{\mathrm{tg}}\nolimits \alpha = \frac{a}
{c}\)
\(\sin \alpha = \frac{a}
{c}\)
\(\cos \alpha = \frac{b}
{a}\)
\(\mathop{\mathrm{cotg}}\nolimits \alpha = \frac{b}
{a}\)
