Webb$\begingroup$ I suppose your confussion stems from the fact that some pretty well-known scientific calculators (e.g., at least some of the Casio ones) denote by $\,\sin^{-1}\,,\,\cos^{-1}\,,\,\tan^{-1}\,$ the inverse trigonometric functions...a very poor, sloppy choice by those Casio guys, and since these calculators are very widely used by high …

WebbWe know that the domain of the cosine function is R, that is, all real numbers and its range is [-1, 1]. A function f(x) has an inverse if and only if it is bijective(one-one and onto). Since cos x is not a bijective function as it is not one-one, the inverse cosine cannot have R as its range.Hence, we need to make the cosine function one-one by restricting its domain. flamethrower inventedWebbIn geometry, a cardioid (from Greek καρδιά (kardiá) 'heart') is a plane curve traced by a point on the perimeter of a circle that is rolling around a fixed circle of the same radius. It can also be defined as an epicycloid having a single cusp.It is also a type of sinusoidal spiral, and an inverse curve of the parabola with the focus as the center of inversion. can plantar fasciitis cause ankle problemsWebbTrigonometrisk funktion.
