y-(any value of the function)=0.5(x-(any value in the domain))

e.g. Point with point A being (1,14) The answer would be y-14=0.5(x-1)

We need to understand both what this question is asking of us, and what the question tells us. We are asked to investigate the motion of the parachutist, therefore in this case we need to apply Newton’s L...

It is important to remember, having an accent is normal. You can live in the country for decades and still have an accent. It is however equally important that you pay attention to the intonation of a lan...

cos(x) + (1/2)sin(x) :

Rsin(x + a) = R{sin(x)cos(a) + cos(x)sin(a)} = (1/2)sin(x) + (1)cos(x) (comparing coeffs.)

Therefore Rcos(a) = 1/2 and separately Rsin(a) = 1 So tan(a) = 2 and R^2 =...

A general way of solving these equations is getting them to the form sin(y)=k. In this case, to do so, we have to divide by 2 and then put y=3x+45° We then get si...
