Find the exact value of sin pi/12

Use subtraction properties to find sin pi/12

[mathematicssolved]

that's correct, rationalizing the denominator gives sqrt(2)/2 also. Both are correct.

SenX x CosY - SenY x cos X
cos (A+B) = cosA cos B - Sen A Sen B

shouldnt the formula equal SinCos - CosSin ?? and not minus sin cos ?

[eastonhousworth]

What would the answer be if it asked for csc Pi over 12??

[DarkerApollo]

sin(7pi/12)(sin9pi/12-2pi/12) = (sqrt(6)+sqrt(2))/4 because sin(3pi/4)=sin(pi/4) but cos(3pi/4)= -cos(pi/4)
