Find the following exact values. NO calculators! All angles are in RADIANSs. a) cos^-1 1 b) sin^-1 Squareroot 2/2 c) tan^-1 1 d) cos^-1 1/2 e) arcsin 1/2 f) arctan Squareroot 3 g) arccos 0 h) csc^-1 2

Solution

a)cos^-11 = 0

b)sin^-1(2_/2) =_/4

c)tan^-11 =_/4

d)cos^-1(1_/2) = _/3

e)arcsin^-1(1_/2) = _/6

f)arctan^-1(3) = _/3

g)arccos0=_/2

h)csc^-1(2) =sin^-1(1_/2) =_/6
