1. Procedural memory concerns motor skills and actions, such as riding a bike. Episodic memory concerns life events, such as a birthday party. 2. Procedural memory is non-declarative, meaning it is dif...

Since tanx = sinx / cosx that means that the inverse of tan must = the inverse of sinx / cosx which is cosx / sinx . So we know that 1/tanx = cosx . Now all we have to do is apply the multiple 4/7 becaus...

A straight line equation is defined as y=mx+c where m is the gradient and c is the intercept. Since the gradient is already said to be 3 we can substitute this in to mean the equation for AB is y=3x+c. Si...

One reason for gender differences in educational achievement is the impact of feminism. Feminism has encouraged girls ambition and widened their perceived life choices thus encouraging female achievement ...

5cos³x = 5cosxFirstly -5cosx from both sides and divide through by 5We have:cos³x-cosx = 0We can factorise this:cosx(cos²x - 1) = 0 For this to be true either:cosx = 0 or ...
