Sine, Cosine, And Tangent Table: 0 To 360 Degrees, 2017 University of Nebraska-Lincoln

#### Sine, Cosine, And Tangent Table: 0 To 360 Degrees, Paul Royster

##### Math Department: Class Notes and Learning Materials

In helping with my high school student's math homework, I was astonished to find no trig tables in the 800-page textbook. I was further astonished to find no printable version online that extended beyond 90°.

While most smartphones will tell you the sine of an angle, they will not necessarily tell you the angle for which the sine is x. And since multiple angles may have the same sine (e.g. 59° and 121°), it seems useful to see the numerical progression of the functions in addition to their graphical representation.

Here is a printable sine-cosine-tangent table for all integer angle …

Series Solutions Of Polarized Gowdy Universes, 2017 Virginia Commonwealth University

#### Series Solutions Of Polarized Gowdy Universes, Doniray Brusaferro

##### Theses and Dissertations

Einstein's field equations are a system of ten partial differential equations. For a special class of spacetimes known as Gowdy spacetimes, the number of equations is reduced due to additional structure of two dimensional isometry groups with mutually orthogonal Killing vectors. In this thesis, we focus on a particular model of Gowdy spacetimes known as the polarized T3 model, and provide an explicit solution to Einstein's equations.

On A Double Integral Involving The I-Function Of Two Variables, 2016 P.A. College of Engineering, India

#### On A Double Integral Involving The I-Function Of Two Variables, Shantha K. Kumari, Vasudevan T. M. Nambisan

##### Applications and Applied Mathematics: An International Journal (AAM)

In this paper we establish an interesting double integral involving the I-function of two variables recently introduced in the literature. Since I-function of two variables is a very generalized function of two variables and it includes as special cases many of the known functions appearing in the literature, a number of integrals can be obtained by reducing the I-function of two variables to simpler special functions by suitably specializing the parameters. A few special cases of our result are also discussed.

Explicit formulae which express the generalized Laguerre expansion coefficients for the moments of the derivatives of any differentiable function in terms of the original expansion coefficients of the function itself are given in the matrix form. In the scheme, by using this approach we reduce solving the linear differential equations to solving a system of linear algebraic equations, thus greatly simplify the problem. In addition, several numerical experiments are given to …
