The inexact value of tan 330 is -0.577350, to six significant places. The exact value cannot be represented as a single number because it is a non terminating decimal. To represent it exactly, consider that tan x is sin x over cos x, and that sin 330 is -0.5 and cos 330 is square root of 0.75. As a result, the exact value of tan 330 is -0.5 divided by square root of 0.75.
tan u/2 = sin u/1+cos u
0.34202014332566873304409961468226
The exact value is 0.5*sqrt(3)
1.570796327
The exact value of sin 22.5 is 0.382683432
what is the value of sin 75 degree
The exact value is 0.40673664.
sin(405) = square root of 2 divided by 2 which is about 0.7071067812
sin 480° is equal to sin 60°, which is sqrt(3)/2 or approximately 0.866.
sin(60 degrees) = 0.8660 approx. The exact value is sqrt(3)/2.
SQRT(3)/4 - 1/4
1/squareroot2 ummm, yes, but be aware that square root 2 is an irrational number that has *no* exact value. So your question cannot be answered in the terms you asked it. You can use a calculator to get as much precision as you want, but never an *exact* answer.
