What seven points of x can I put on the x axis over the interval -2pi less than or equal to x less than or equal to 2pi

Is the exact value of sin(pi/3) + cos(pi/6) equal to 1.73?

I 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

SO my answer would be sqrt 3?

• trig -

If you are supposed to give exact answer, the only one is sqrt 3
