**Anna**, Thursday, April 17, 2008 at 7:09pmIs the exact value of sin(pi/3) + cos(pi/6) equal to 1.73?

**Damon**, Thursday, April 17, 2008 at 7:47pmI do not understand Randy's question.

Anna

sin (pi/3) = (1/2) sqrt 3

cos (pi/6) = (1/2) sqrt 3

sum = sqrt 3 exactly

However sqrt 3 is an irrational number. It can not be expressed exactly by 1.73 or 1.732050808 or any other integer plus decimal fraction

**Anna**, Thursday, April 17, 2008 at 7:56pmSO my answer would be sqrt 3?

**Damon**, Thursday, April 17, 2008 at 8:51pmIf you are supposed to give exact answer, the only one is sqrt 3
