Power series

In mathematics, a power series (in one variable) is an infinite series of the form where an represents the coefficient of the nth term and c is a constant. Power series are useful in mathematical analysis, where they arise as Taylor series of infinitely differentiable functions. In fact, Borel's theorem implies that every power series is the Taylor series of some smooth function. In many situations, c (the center of the series) is equal to zero, for instance when considering a Maclaurin series.

Taylor series

In mathematics, the Taylor series or Taylor expansion of a function is an infinite sum of terms that are expressed in terms of the function's derivatives at a single point. For most common functions, the function and the sum of its Taylor series are equal near this point. Taylor series are named after Brook Taylor, who introduced them in 1715. A Taylor series is also called a Maclaurin series when 0 is the point where the derivatives are considered, after Colin Maclaurin, who made extensive use of this special case of Taylor series in the mid-18th century.

Trigonometric functions

In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others. They are among the simplest periodic functions, and as such are also widely used for studying periodic phenomena through Fourier analysis.

2019 Maharashtra Legislative Assembly election

The 2019 Maharashtra Legislative Assembly election was held on 21 October 2019 to elect all 288 members of the state's Legislative Assembly. After a 61.4% turnout in the election, the ruling National Democratic Alliance (NDA) of the Bharatiya Janata Party (BJP) and Shiv Sena (SHS) won a majority. Following differences over the government formation, the alliance was dissolved, precipitating a political crisis. Since a council of ministers had not been formed after no party could manage to form the government, President's rule was imposed in the state.

1998 Winter Olympics

The 1998 Winter Olympics, officially known as the XVIII Olympic Winter Games and commonly known as Nagano 1998 (長野1998), was a winter multi-sport event held from 7 to 22 February 1998, mainly in Nagano, Japan, with some events taking place in the nearby mountain communities of Hakuba, Karuizawa, Nozawa Onsen, and Yamanouchi. The city of Nagano had previously been a candidate to host the 1940 Winter Olympics (which were later cancelled), as well as the 1972 Winter Olympics, but had been eliminated at the national level by Sapporo on both occasions.
