The value of sin2 π/7+sin4 π/7+sin8 π/7 | sin2pi/7+sin4pi/7+sin8pi/7 #challenge #projecteducation
prove that: sin2pi/7 + sin4pi/7 + sin8pi/7 = (root7)/2
How do you simplify sin((2pi)/7)+sin((4pi)/7)+sin((8pi)/7)
show that `sin (2pi/7) + sin(4 pi/7) + sin (8 pi/7) = sqrt7/2`
How can find the value of sin 2pi/7 + sin 4pi/7 +sin 8pi/7?
trigonometry challenging question
cos pi/7+cos 2 pi/7+cos3pi/7
