depending on the grade of the formula they can be called lines - 1st degree -, hyperbole - 2nd degree -, ... generally speaking all of them are called splines.
Bezier
An algorithm, perhaps.
The procedure is called pericardial thoracentesis.
Because there was no IBM-PC-standard graphic format, individual programmers developed their own ways to describe a graphic on the screen. These different ways are called graphics formats.
The answer to a mathematical problem is called a "solution." In the context of equations, the solution is the value or set of values that satisfy the equation. For problems involving more complex scenarios, the term "result" may also be used to describe the final answer after all calculations are completed.
In mathematical terms it's called a rhombus.
Insertion of a metal coil, called a stent, that can be implanted permanently to keep a blocked artery open. This stenting procedure is becoming more common.
Raster Graphics
A mathematical rule can be called many things including a theory. Proofs can prove this theory to be a rule.
Yes, they are called graphics.
This procedure is called CPR.
I can think of three: raster graphics, vector graphics and 3D graphics. Raster graphics are composed of pixels, per say, dots of different values of red, green, blue and alpha (transparency value) or RBGA as it is usually called. It can also be cyan, magenta, yellow and black or CMYK. Vector graphics are composed of vertexes and handles that control the the curvature of lines, this lines can be shown or used to describe color masses (shapes) which can have effects applied to them. 3D graphics have to mayor ways to describe the shapes. One is using vector graphics with an added depth coordinate value and then applying surfaces to the lines. The other one is placing vertexes in and then adding surfaces between them, usually between three or four (called polygons), but there can be more depending on the program. After the 3D shapes have been described, a 2D image can be mapped to it's surface.
