Each of these functions are derived in some way from sine and cosine. The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x . ... The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

arcsin is the inverse of the sin function. Meaning that sin(arcsin(x)) = x. (note that arcsin is multi-valued, so arcsin(sin(x)) need not always be x). cosecant is the reciprical of the sin function or 1/sin(x) so that csc(x)*sin(x) = 1 when it is defined.

Using Even and Odd Properties of Trigonometric Functions Secant is an even function. The secant of an angle is the same as the secant of its opposite. So if the secant of anglet t is 2, the secant of−t − t is also 2.

UVXY is mathematically guaranteed to trend towards zero in the long run. You'll never lose more than your original investment, but it's sort of just a waste of money to hold it. ... If fact, UVXY reverse split 5 times in its first four years of existence—which may be a record. The last reverse split was a 5:1.

Sensex is calculated using the "Free-float Market Capitalization" methodology. ... The calculation of Sensex involves dividing the Free-float market capitalization of 30 companies in the Index by a number called the Index Divisor. The Divisor is the only link to the original base period value of the Sensex.

Arccos definition The arccosine of x is defined as the inverse cosine function of x when -1≤x≤1. When the cosine of y is equal to x: cos y = x. Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y: arccos x = cos-1 x = y.
