what is the value of sin 75 degree

The exact value is 0.40673664.

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.

405 is exactly 9 times the square root of five . The square root of 5 is irrational and can only be approximated with decimals.

SQRT(3)/4 - 1/4

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.

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.

tan u/2 = sin u/1+cos u

what is the value of a 100 sin sundert mark

sin(40o) = 0.6428

It is: sin(90) = 1

It is: sin(62) = 0.8829475929.

It is:- sin(40) = 0.6427876097

If tan 3a is equal to sin cos 45 plus sin 30, then the value of a = 0.4.

mostly it comes from memorization. If sin 30 = 1/2, then arcsin (1/2) = 30

Some value / exact value x 100 = percentage

There is an exact value - we just can't write it in numbers.

Approximate value, is a value that is not necessarily the right answer but, it is the closest one to it.It means that it isn't exact - but close to the exact value.

sin(35 deg) = 0.5736

Y=sin X is a function because for each value of X, there is exactly one Y value.

The exact value is 0.5*sqrt(3)

Sin(x) has a maximum value of +1 and a minimum value of -1.

type the value of sine in the calculator and press 2ND SIN for sin-1, or press 2ND SIN for sin-1 and type the value of sine, because -sin(.xxxx) = angle known as inverse sine
