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...
A general method would be to compute a and b with the general solution formula for quadratic equations. However, a special property of quadratic equations can make this a...
Hard engineering is a method of coastal management that involves the building of large and generally expensive features in order to defend against the sea,this usually includes building sea walls, groynes...
A normal fault is a fault that involves extensional movement along its fault plane, this involves the hanging wall moving down in relation to the footwall. A reverse fault involves contraction along its f...
