Grade 11 Reduction Formula

Write the following in terms of a single trigonometric ratio:
 $\tan(180°−θ)×\sin(180°+θ)$  

Simplify $\frac{\tan(180°+θ)\cos(180°−θ)}{\sin(180°−θ)}$  

Simplify $\frac{\tan(180°−θ)\sin(360°+θ)}{\cos(180°+θ)\tan(360°−θ)}$  

Simplify $\frac{\sin(360°+α)\tan(180°+α)}{\cos(360°−α)\tan^2(360°+α)}$  

Simplify $\cos^2(360°+θ)+\cos(180°+θ)\tan(360°−θ)\sin(360°+θ)$  

Simplify $\frac{\cos(90°+θ)\sin(θ+90°)}{\sin(−θ)}$  

Simplify $\frac{2\sin(90°−x)+\sin(90°+x)}{\sin(90°−x)+\cos(180°+x)}$  

Simplify $\sin(360°−θ)\cos(180°−θ)\tan(360°+θ)$  

Simplify $\frac{\cos(360°+θ)\cos(−θ)\sin(−θ)}{\cos(90°+θ)}$  

 $\frac{\sin(180°+α)\tan(360°+α)\cosα}{\cos(90°−α)}$
