Find the exact value of sec 30 degree sec 30 degree Simplif

Find the exact value of sec 30 degree. sec 30 degree = (Simplify your answer, including any radicals. Us

Solution

we know that sec = 1/(cos)

cos(30^o) = (3)/2

==> sec(30^o) = 1/(cos(30^o))

==> sec(30^o) = 1/[ (3)/2]

==> sec(30^o) = 2/3

==> sec(30^o) = (2/1.73205)

Hence sec(30^o) = 1.1547
