      • Once we have the restricted function, we are able to proceed with defining the inverse cosine function, cos -1 or arccos. • The inverse of the restricted cosine function y= cos x, 0 < x < π, is y= cos -1 x and y = arccos x. • Which also means, cos y = x, where 0 < y < π, -1< x < 1 (Remember, the domain of f is the range of f -1, and ...

The inverse trigonometric functions: arcsin and arccos The arcsine function is the solution to the equation: z = sinw = eiw − e−iw 2i. ∗In our conventions, the real inverse tangent function, Arctan x, is a continuous single-valued function that varies smoothly from − 1 2π to +2π as x varies from −∞ to +∞. In contrast, Arccotx

      cos(sin 1(x)) 2 = 1 cos(sin 1(x)) 2 = 1 x2 cos(sin 1(x)) = p 1 x2 Now the question is: Which do we choose, p 1 x2, or p 1 x2, and this requires some thinking! The thing is: We defined sin 1(x) to have range [ˇ 2; ˇ 2] so, cos(sin 1(x)) has range [0;1], and is in particular 0 (see picture below for more clarification). So, since cos(sin 1(x ...

      ‘arc’ in ‘arccosine’, recall that an inverse function, by de nition, reverses the process of the original function. The function f(t) = cos(t) takes a real number input t, associates it with the angle = tradians, and returns the value cos( ). Digging deeper,2 we have that cos( ) = cos(t) is the

      Inverse Trigonometric Functions If x=sin(y), then y=sin-1(x), i.e. s is the angle whose sine is y. In other words, x is the inverse sine of y. Another name for inverse sine is arcsine, and the notation used is y=arcsin(x). Similarly, we can define inverse cosine, inverse tangent, inverse cotangent, inverse secant and inverse cosecant.
