1 dzień temu · Seven circles, each with radius 1, overlap to form the composite figure shown above. Find the area of the shaded region.
4 dni temu · I am working on a visualisation project where I am attempting to create a circle illusion using moving dots along the diameters of a larger circle. To achieve this effect, I need to calculate the initial starting positions of these moving dots. Imagine two circles: A larger circle with radius R centred at (0, 0).
3 dni temu · We can obtain a sphere by revolving half a circle about the \(x\)-axis. This circle can be parameterized as \(x(t)=r\cos(t) \) and \(y(t) = r\sin(t) \) for \(0 \leq t \leq \pi \). From this, we get \[ \frac{dx}{dt} = -r\sin(t), \quad \frac{dy}{dt} = r\cos(t) .\] Substituting in our equations for surface area gives
1 dzień temu · A simple example of a regular surface is given by the 2-sphere {(x, y, z) | x 2 + y 2 + z 2 = 1}; this surface can be covered by six Monge patches (two of each of the three types given above), taking h(u, v) = ± (1 − u 2 − v 2) 1/2. It can also be covered by two local parametrizations, using stereographic projection. The set {(x, y, z ...
