Curves which do not dominate other curves

Let $g>1$ be an integer. Does there exist a (smooth projective) genus g curve $X$ which doesn`t dominate a curve of positive genus and genus smaller than $g$?
Surely such curves exist. Just take a curve with simple jacobian.

A three-dimensional vector field A (r) is specified by three components that are, individually, functions of position. It is difficult enough to plot a single scalar function in three dimensions;
a plot of three is even more difficult and hence less useful for visualization purposes.

Rotations in Complex Plane
You're notation is still hard to follow. For instance, the letter z is usually used to express a complex number. z = x+iy.
There are some basic tools you need to perform operations on complex numbers.

Jacobs Physics
Most textbooks define work and kinetic energy, then show the connection: the net work done on an object is equal to the change in that object’s kinetic energy.
My students have always had difficulty with this principle.
