solomonzelman · Answer

is the first thing here  `sin²x`  or  `sin(2x)`   ?

solomonzelman · Answer

solomonzelman · Answer

$\normalsize\color{blue}{  \sin^2x−\sin(x)−2\sin(x)− 2   }$

$\normalsize\color{blue}{  \sin x(\sin(x)-1)−2(\sin(x)− 1)   }$

$\normalsize\color{blue}{  (\sin x−2)(\sin x− 1)   }$

I am in trouble... are you sure you wrote the question correctly ?

rosales0228 · Answer

yeah I copied and pasted it

solomonzelman · Answer

you messaged me, saying `sin²(-x)`   so it is not  $\normalsize\color{blue}{\sin 2(-x)−\sin x−2\sin x−2   }$   , right?

solomonzelman · Answer

Just       $\normalsize\color{blue}{\sin^2x−\sin x−2\sin x−2   }$        ?
