Since $$\frac{x}{1+x^2}=\int_0^\infty e^{-y}\sin (xy) \, dy,$$ we have that $$I=\int_0^\infty \frac{\cos bx}{1+x^2} \, dx=\int_0^\infty \frac{\cos bx}{x} \, dx \int_0^\infty e^{-y}\sin (xy)\, dy.$$ Changing the order of integration (which can...
The sin, cos and tan functions along with their inverts are located in the Math class. To do what you want would be: a = Math.asin(x / r); I'm not sure what you mean by sin^(-1) == sec. The secant function is the reciprocal of the cosine so you would get it by doing...
An arithmetic operation apparatus performs an arithmetic operation of a differentiable elementary function including a sine function sin(x), a cosine function cos(x), arc tangent function arctan(x), an exponential function e , a logarithm function loge(x), an inverted number 1/x, a square ...
The KT and KR keyboard/display units are unique in that they include a transistorized sequencing unit built into the keyboard unit that provides ROM-based programs for calculating sin, cos, sin-1, and tan-1 functions. The keys for these functions are at the upper-left of the keyboard as ...
