sin20sin40sin80

OpenStudy (1davey29):

Assuming this is in degrees not radians, sin(20) is roughly .342, sin(40) is roughly .643, and sin(80) is roughly .985. Is the question asking to multiply them or just find their values?

OpenStudy (bhaktharvali):

answer is (root 3)/8, but how to get it??

OpenStudy (bhaktharvali):

thank you....
