do my maths homework <.<

[Arca_]

ok so i&#39;m starting 12th year and took extra maths class to prepair for belgium&#39;s polytechnic exam so basically what we do are exercices from those exams and we&#39;re reviewing trigonometry and this exercice has been messing with me for like 2 hours I can&#39;t do it so festo or someone a lil bit smart help me out pls

if a+b+c+d=2pi

show that:

sin a + sin b + sin c + sin d = 4sin[(a+b)/2]sin[(b+c)/2]sin[(a+c)/2]


i&#39;ll be wery thanksful if smone help me out with this <.<

all i know is you have to get rid of sin d since it&#39;s not back on the right side so what I did was

d = 2pi - (a+b+c)

sin d = sin (2pi-[a+b+c])
sin d = -sin (a+b+c)

good luck guys gonna go study french <.<
