Semicircle - Shape, Definition, Properties, Examples - Cuemath
A semicircle is a closed 2D shape . It is not a polygon since it has a curved edge. A semicircle has one curved edge which is its circumference and 1 straight edge which is called its diameter. It is exactly half of the circle. The diameter of the circle and the two semicircles formed out of it are the same. www.cuemath.com

Parametrization of half circle in complex plane I'm looking for a parametrization of the half-circle in the upper plane, going from $-1$ to $1$. Is $$\gamma(t):\begin{cases}[0,\pi]\to\mathbb C\\\t\mapsto-e^{-it}\end{c...
. $$ \gamma(t) = -e^{-it} = e^{i(\pi - t)} \quad (0 \le t \le \pi) $$ is an arc on the unit circle with the argument of $\gamma(t)$ decreasing from $\pi

Find area of triangle in half circle !enter image description here Half circle with $r = 2$. So, think $CD = BD = 2, CEB$ = right triangle Area = $ 1/2 \overline{CE}\ \overline{AB}$ What is the max area? By theory ...
Hint: $$Area = \frac{1}{2}bh$$ where $b$ is the base of the triangle and $h$ is the height. As $r=2$, the diameter must be $4$ and so the base of the triangle must be $4$. To find the maximum height, observe that the triangle would be the largest when $h=r$, as you suggested. So, consider $$Area = \...

Parametrization of a half circle in a different interval other than from 0 to $\pi$. If I have a half circle parametrization such that $e^{it}$, $0 \leq t \leq \pi$, to get the parameterization of the same circle on i...
Since we can map this interval onto the interval $[0,\pi]$ via $\pi\left(\frac{t-a}{b-a}\right)$, we can have any interval $[a,b]$ parametrize the top half of the unit circle by $$ \exp{i\left(\pi\frac{t-a}{b-a}\right)}.$$ In your particular case, if you're paramtrizing this circle for $0\leq t\leq 1$, then

Finding the perimeter and area of a rectangle within a half-circle It's another late night studying calculus and I can't make heads or tails of this question. Perhaps somebody could help clarify it for me. I have a ha...
For a given $x$ we can find $y$ as $\sqrt{9-x^2}$. So we get the points $(x,\sqrt{9-x^2})$ for $R$ and $S$. So the width is given by $2x$ and the height by $\sqrt{9-x^2}$. Perimeter: $4 x + 2 \sqrt{9 - x^2}$ Area: $2 x \sqrt{9 - x^2}$
