Volume with Rings. To get a solid of revolution we start out with a function, y=f (x), on an interval [a,b]. We then rotate this curve about a given axis to get the surface of the solid of revolution. For purposes of this discussion let’s rotate the curve about the x -axis, although it could be any vertical or […]

Double angle trigonometric equation
Double angle equations are allowing the expression of trigonometric functions of angles equal to 2u in terms of u. The double angle formulas can simplify the functions and gives ease to perform more complex calculations. The double angle formulas are useful for finding the values of unknown trigonometric functions. Therefore in double angle equation we need to consider two rotation. […]
Binomial Distribution
The Binomial distributions Number of successes in a specified number of independent trials of an experiment . Symbol: B (n, p), where n is the number of trials and p the probability of success in each. As there are two parameter therefore it is Binomial distribution. Hence it used for discrete values. binomial distribution
A Double angles identity
A Double angles identity is written2θ, for example, as sin 2θ, cos 2α, or tan 2x, where 2θ, 2α, and 2x. The angle measures and the assumption is that you mean sin(2θ), cos(2α), or tan(2x). Because tangent is equal to the ratio of sine and cosine . Therefor its identity comes from their double-angle identities. double angle identity

Integration of Polynomials
In integration the power of polynomials increase like quadratic become cubic etc. As well as get integration constant . It always give general solution due to integration constant. Integration
Integration by Parts
By parts apply for integration when different functions are in product form . As well as one derivative of another. By parts
