jika
m=cos 2p + cos 2q
dan p-q=150 drajat,
maka nilai "m" adalah?

tak geredna rumuse bae ben mikir dewek Ngikik kiye jangan2 PR... snengen dong digarapna Ngikik maning ::

Sum / Difference of Angles Formulas.

1. cos(A + B) = cos A cos B – sin A sin B

2. cos(A – B) = cos A cos B + sin A sin B

3. sin(A + B) = sin A cos B + cos A sin B

4. sin(A – B) = sin A cos B – cos A sin B

5. tan(A + B) = [ tan A + tan B ] / [ 1 - tan A tan B]

6. tan(A – B) = [ tan A - tan B ] / [ 1 + tan A tan B]



Sum / Difference of Trigonometric Functions Formulas.

7. sin A + sin B = 2 sin [ (A + B) / 2 ] cos [ (A - B) / 2 ]

8. sin A – sin B = 2 cos [ (A + B) / 2 ] sin [ (A - B) / 2 ]

9. cos A + cos B = 2 cos [ (A + B) / 2 ] cos [ (A - B) / 2 ]

10. cos A – cos B = – 2 sin [ (A + B) / 2 ] sin [ (A - B) / 2
]


Product of Trigonometric Functions Formulas.

11. 2 sin A cos B = sin (A + B) + sin (A – B)

12. 2 cos A sin B = sin (A + B) – sin (A – B)

13. 2 cos A cos B = cos (A + B) + cos (A – B)

14. 2 sin A sin B = – cos (A + B) + cos (A – B)



Multiple Angles Formulas.

15. sin 2A = 2 sin A cos A

16. cos 2A = cos 2 A – sin 2 A = 2 cos 2 A – 1 = 1 – 2 sin 2 A

17. sin 3A = 3 sin A – 4 sin 3 A

18. cos 3A = 4 cos 3 A – 3 cos A



Power Reducing Formulas.

19. sin 2 A = (1/2) [ 1 - cos 2A ]

20. cos 2 A = (1/2) [ 1 + cos 2A ]
