How can the exact value of sin75 be found using sina plus b equals sinacosb plus cosasinb?
sin75 = sin(45 + 30) = sin45cos30 + cos45sin30 = (1/root 2)((root 3)/2) + (1/root 2)(1/2)
What does the approximate value mean in math?
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.
How do you divide by exact value and make it a percent?
Some value / exact value x 100 = percentage
How do you use sum and difference identities to find the exact value of sin75?
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
Could you find the circumference of a circle using the exact value for pi?
Yes, you could if you knew the exact value for pi as well as the diameter of the circle. Multiply the diameter by the exact value for pi to get the circumference. However, it is impossible because the exact value for pi is not known. It is only known to about a trillion decimal places, but the exact value is not known.

What is it that you can't ever calculate?
-- end of the universe -- the day you will die -- the exact value of 'pi' -- the exact value of ' e ' -- the exact value of sqrt(2) -- the exact value of any other irrational number

Why not is there an exact value of pie?
There is an exact value - we just can't write it in numbers.
How do you divide by exact value and make it a percent?
Some value / exact value x 100 = percentage
What does number close to an exact value mean?
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
