If sin α = 1/2, then find value of 3 sin α - 4 sin3 α.

1.	If sin α = 1/2, then find value of 3 sin α - 4 sin3 α.
Answer» Given, sin α = 1/2, then 3 sin α - 4 sin³ α = 3 x 1/2 - 4 x (1/2)³ ^{= 3/2 - 4/8} ^{= 1}

Answer»

Given, sin α = 1/2,

then 3 sin α - 4 sin³ α = 3 x 1/2 - 4 x (1/2)³

^{= 3/2 - 4/8}

^{= 1}
