## Compound Angle Formulae

New Topic: Compound Angle Formulae, MiA Unit 2 Ch3

By the end of this topic you will be able to:

â€¢ know and apply the addition formulae:
sin(A+B) = sinAcosB + cosAsinB
sin(Aâ€“B)Â Â = sinAcosB â€“ cosAsinB
cos(A+B) = cosAcosB â€“ sinAsinB
cos(Aâ€“B) = cosAcosB + sinAsinB

â€¢ know and apply the double angle formulae:
sin2AÂ  = 2sinAcosA
cos2A = cos2A â€“ sin2A = 2cos2A â€“ 1

â€¢ apply trigonometric formulae in solution of geometric problems

â€¢ solve trigonometric equations using compound angle formulae
