Trigonometri

1. Persamaan Trigonometri

1.1. sin x : sin a x : a + k.360°Vx =(180-a) + k.360°

1.2. tan x = tan a x = a + k.180

1.3. cos x = cos a x = a + k.360°V x= -a + k.360°

2. Rumus perkalian Trigonometri

2.1. sin A sin B =-½ [cos (A+B)- cos (A+B)]

2.2. cos A cos B =½ [cos(A+B) + cos (A-B)]

2.3. sin A cos B =½ [sin (A+B)+ sin ( A-B)]

2.4. cos A sin B =½ [sin (A+B) - sin (A-B)]

3. Aplikasi turunan

3.1. F.turun: f'(x):<0

3.2. F.naik: f'(x):>0

3.3. PGS : y-y1=m(x-x1) m =y¹
