In geometry, the other name for triangular pyramid is also taken as the tetrahedron that is composed of four triangular faces and six straight edges, and four vertex corners. This could also be defined as the simplest form of ordinary convex polyhedron having only fives faces less than five. Area of One Face of Regular […]

Integration or Integral Calculus is usually passed as the Integral calculus and defined as the reverse operation of the differential calculus. It is true in certain cases but does not capture the true essence of it.  Integration is an important part of mathematics that was introduced earlier to differentiation. \[\large \int_{a}^{\infty}f(x)dx=\lim_{b\rightarrow \infty}\left [ \int_{a}^{b}f(x)dx\right ]\] […]

The Riemann summation method is needed to calculate the approximation of area under curves. In the case of right and left methods, the approximation is performed using right or left endpoints for each subinterval respectively. There are minimum or maximum methods to give approximation with the help of smaller or larger endpoints for each of […]

There are various student are search formula of (a-b)^3 and a^3-b^3. Now I am going to explain everything below. You can check and revert back if you like. you can also check cube formula in algebra formula sheet.   a2 – b2 = (a – b)(a + b) (a+b)2 = a2 + 2ab + b2 a2 + b2 = (a – […]

Population Variance Formula The population Variance Formula in mathematics is sigma squared equals the sum of x minus the mean squared divided by n. \[\ \huge \sigma^{2}=\frac{\sum\left(x-\overline{x}\right)^{2}}{n}\] The variance of a sample is defined by slightly different formula: \[\ \huge S^{2}=\frac{\sum\left(x-\overline{x}\right)^{2}}{n-1}\] Where, \[\ \sigma^{2}$= Variance\] x = Item given in the data \[\ \overline{x} = […]
