Section 6.3 Inverse Trig Functions 423 The sin −1 ( )x is sometimes called the arcsine function, and notated arcsin ( )a. The cos −1 (x) is sometimes called the arccosine function, and notated arccos ( )a. The tan −1 ( )x is sometimes called the arctangent function, and notated arctan ( )a. The graphs of the inverse functions are shown here: sin −1 ( )x cos −1 ( )x tan −1 ( )x

2 = 1 x2 + 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 ...

Example 2: cos (cos -1 0.6) Answer: Since -1 < 0.6 < 1, then cos (cos -1 0.6) = 0.6 because the form is following the cosine-inverse cosine identities. Example 3: arccos (-1/√2) Answer: • arccos (-1/√2), is the same as cos y= -1/√2,where 0< y < π. • Due to the fact, that the figure displays a mirror image of π/4 on the II quadrant,

The graph of the function given by y = cos–1 x can be drawn in the same way as discussed about the graph of y = sin–1 x. The graphs of y = cos x and y = cos–1x are given in Fig 2.2 (i) and (ii). Fig 2.2 (ii) Let us now discuss cosec –1x and sec x as follows: Since, cosec x = 1 sin x, the domain of the cosec function is the set {x: x ∈ ...

Inverse Trigonometric Functions: •The domains of the trigonometric functions are restricted so that they become one-to-one and their inverse can be determined. •Since the definition of an inverse function says that -f 1(x)=y => f(y)=x We have the inverse sine function, -sin 1x=y - π=> sin y=x and π/ 2
