To derive the arc length formula, let us recall what is the circumference of a full circle whose radius is 'r'. It is 2πr. But arc is just a part (in fact afraction) of the total circumference. We know that the angle at the center in a full circle is 360°. If the angle su...
The steps to derive this formula are: Define a full circle/revolution as 360 degrees or 2π radians. Set up a proportion: degrees/360 = radians/2π Cross-multiply: degrees = (radians * 360)/2π Simplify by dividing both sides by 2: degrees = (radians * 180)/π To convert from radi...
First, a series of quality checks were run on the retinotopy data to determine the quality of the maps in adults and children. Our primary research questions concern the surface area of either whole visual maps or parts of these maps. The boundaries of these maps are defined by polar angle ...
In the next example we use multisource Digital Elevation Data to construct most accurate land surface model of an area, and then use R, GDAL, SAGA GIS and GRASS GIS to derive some DEM derivatives and classify landforms using the 30 m resolution land surface model (DLSM). The study area ...

theta is equal to cosec theta. in the same way, we can derive the formula for sec 90 degrees plus theta. sec(90° + θ) = -cosec θ examples on sec 90 value question 1 : what is the value of sec(270 – x) sec(90 – x) – tan (270 – x) tan (90 – x)? solution : ...
Despite the widespread use of prescribed fire throughout much of the southeastern USA, temporal considerations of fire behavior and its effects often remain unclear. Opportunities to burn within prescriptive meteorological windows vary seasonally and alo
The Basic Arc of the Story As I’ve explained elsewhere, I think I now finally understand the Second Law of thermodynamics. But it’s a new understanding, and to get to it I’ve had to overcome a certain amount of conventional wisdom about the Second Law that I ...
Now why divide or multiply a particular notation symbol by its base to derive other bases. It’s basically math common sense. You just take a representation, and decide by the 'tumbler capacity’ to get the total number of items that is being counted, which makes sense does it not? Say...
