WebThe Area of a Parabola calculator computes the area of a parabola section based on the distance (a) from the apex of the parabola along the axis to a point, and the width (b) of the parabola at that point perpendicular to the axis. WebAug 31, 2024 · John P Snyder, author of many useful articles and books on map projections, created an equal-area projection called (in an aversion of Stigler’s Law) Snyder’s equal-area projection.1 Snyder’s projection was designed for polyhedral globes and maps. The best-known example of a polyhedral map might be Buckminster Fuller’s Dymaxion map, based …

WebHeron's formula is used to find the area of a triangle when the length of the 3 sides of the triangle is known. To use this formula, we need to know the perimeter of the triangle which is the distance covered around the triangle and is calculated by adding the length of all three sides. Heron’s formula has two important steps. Step 1: Find the semi perimeter (half … WebDec 22, 2016 · Use the following determinant formula which gives twice the (signed) area of the triangle a->b->c. If the area is positive, then a->b->c is counterclockwise; if the area is negative, then a->b->c is clockwise; if the area is zero then a->b->c are collinear. The second version might be more efficient since fewer multiplications and additions.
