Could someone explain to me please just how the NewXValue() functions use the Sin and Cosine rules to work? Because these functions are kind of confusing me.

Thanks.

x = current location
angle = angle of rotation
dist = distance to move

function newXValue(x, angle, dist)
x = x + cos(angle)*dist
endfunction x

function newZValue(z, angle, dist)
z = z + sin(angle)*dist
endfunction z
