trun it into sin( 45 + 30 ).
sin ( 45 + 30 ) = sin30cos45 + cos30sin45
sin30cos45 + cos30sin45 = (1/2)((sqrroot2)/2) + ((sqrroot3)/2)((sqrroot2)/2)
(1/2)((sqrroot2)/2) +((sqrroot3)/2)((sqrroot2)/2)=((sqrroot2)/4) + ((sqrroot6)/4)
((sqrroot2)/4) + ((sqrroot6)/4)= ((sqrroot2) + (sqrroot6)) /4
sin75 = sin(45 + 30) = sin45cos30 + cos45sin30 = (1/root 2)((root 3)/2) + (1/root 2)(1/2)
sin(75) = sin(45 + 30) = sin(45)*cos(30) + cos(45)*sin(30) = [1/sqrt(2)]*[sqrt(3)/2] + [1/sqrt(2)]*[1/2] = 1/[2*sqrt(2)]*[sqrt(3) + 1] that is [sqrt(3) + 1] / [2*sqrt(2)]
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.
Some value / exact value x 100 = percentage
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.
sin75 = sin(45 + 30) = sin45cos30 + cos45sin30 = (1/root 2)((root 3)/2) + (1/root 2)(1/2)
what is the value of sin 75 degree
They are identities.
sin(75) = sin(45 + 30) = sin(45)*cos(30) + cos(45)*sin(30) = [1/sqrt(2)]*[sqrt(3)/2] + [1/sqrt(2)]*[1/2] = 1/[2*sqrt(2)]*[sqrt(3) + 1] that is [sqrt(3) + 1] / [2*sqrt(2)]

There is an exact value - we just can't write it in numbers.
The exact value of sin 22.5 is 0.382683432
Some value / exact value x 100 = percentage
3, -3 4, -4 these numbers all have the same "exact value" 3, -5 do not have the same exact value. exact value is how many s[pots away from 0 it is
HKEY_CURRENT_USER\Identities\{VALUE}
The exact value is 0.5*sqrt(3)
