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
