How to find the value of sin300°?
Find the value of given trigonometric function
Given, sin300°
We know that
sinα-β=sinαcosβ-cosαsinβ
Now by substituting the value of α=360° and β=60°in the trigonometric identity we get
sin360°-60°=sin360°cos60°-cos360°sin60°⇒sin360°-60°=0-1×32∵cos360°=1,sin360°=0,cos60°=12andsin60°=32⇒sin300°=-32
Hence the value of sin300° is -32.
