"What is the equation of horizontal ellipse?" in Class XI-XII Tuition (PUC), Mathematics(Class XI-XII Tuition (PUC)), Ellipse
Hi Swarna, any ellipse is horizontal (elongated along x-axis) if its semi-major axis is greater than semi-minor axis (a>b) in canonical equation of ellipse i.e. x2/a2 + y2/b2 = 1, if b>a then it looks vertically elongated and a=b it is circle. You can try some experiments with ellipse here https://www.desmos.com/calculator
"What do you mean by ellipse?" in Class XI-XII Tuition (PUC), Mathematics(Class XI-XII Tuition (PUC)), Ellipse
Ellipses are the closed type of conic section: a plane curve resulting from the intersection of a cone by a plane. In terms of locus, ellipse is a curve in a plane surrounding two focal points such that the sum of the distances to the two focal points is constant for every point on the curve. A circle is a special type of an ellipse having both focal points at the same location. The shape of an ellipse (how 'elongated' it is) is represented by its eccentricity, which for an ellipse can be any number from 0 (the limiting case of a circle) to arbitrarily close to but less than 1.

"What are the measures of central tendency?" in Class IX-X Tuition, Mathematics(Class IX-X Tuition)
Hello Sitaram, There are many measures of central tendency, but most common are Mean, Median and Mode. Arithmetic mean (or simply, mean) – the sum of all measurements divided by the number of observations in the data set. Median – the middle value that separates the higher half from the lower half of the data set. The median and the mode are the only measures of central tendency that can be used for ordinal(can be sorted) data, in which values are ranked relative to each other but are not measured absolutely. Mode – the most frequent value in the data set. This is the ONLY central tendency measure that can be used with nominal(can be classified) data, which have purely qualitative category assignments.
