Show that sin 600° . cos 330° + cos 120° . sin 150° = - 1
I know that sinΘ = opposite/hypotenuse and cosΘ = adjacent/hypotenuse.
The Attempt at a Solution
I am equipped with knowledge about what sinΘ and cosΘ is from right angled triangle.
I stand in front of a wall and visualize opposite side, adjacent side and hypotenuse but I am unable to clearly picture what sin 600° . cos 330° + cos 120° . sin 150° = - 1 mean.
What is the meaning of the equation?
What is the meaning of -1 on the right hand side of the equation?
