###### Answer: C

Notation. Several notations for the inverse trigonometric functions exist. The most common convention is to name inverse trigonometric functions using an arc- prefix: arcsin( x ) arccos( x ) arctan( x ) etc. (This convention is used throughout this article.) This notation arises from the following geometric relationships: [citation needed] when measuring in radians an angle of θ radians will …

Suppose a dependent variable y represents a function f of an independent variable x that is = (). Then the derivative of the function f in Leibniz’s notation for differentiation can be written as (()).The Leibniz expression also at times written dy/dx is one of several notations used for derivatives and derived functions.A common alternative is Lagrange’s notation

Given random variables … that are defined on a probability space the joint probability distribution for … is a probability distribution that gives the probability that each of … falls in any particular range or discrete set of values specified for that variable. In the case of only two random variables this is called a bivariate distribution but the concept generalizes to any …

An attractive fixed point of a function f is a fixed point x 0 of f such that for any value of x in the domain that is close enough to x 0 the iterated function sequence () (()) ((())) … converges to x 0.An expression of prerequisites and proof of the existence of such solution is given by the Banach fixed-point th…
