Question

$\dfrac {\cos 8\left( 1-\cos 16\right) } {\sin 16\left( 1-\cos 8\right) }$

ifadesinin en sade şekli ?

Answer 1

diğer sorulardaki kurallar dahilinde yazıcam anlamadıgını sor!

$cos2x=1-2sin^2x$


$\dfrac{cos8(1-(1-2sin^28))}{2sin8.cos8(1-(1-2sin^24))}=\dfrac{2sin^28}{2sin8(2sin^24)}=\dfrac{2sin4.cos4}{2sin^24}=cot4$
