A synapse is gap between two neurones. When a nerve impulses travels along the axon reaches the end of the pre-synaptic neurone, the release of chemical messengers (called neurotransmitters) is triggered....

4 sin(x) – 8 cos(x)= Rsin(x-a) here use double angle formula

4 sin(x) – 8 cos(x)= Rsin(x)cos(a)-Rcos(x)sin(a) Rearrange so in same format as LHS

4 sin(x) – 8 cos(x)= Rcos(a)sin(x)-Rsin(a)cos...
