In my class notes my professor defined a true vector as a vector which does not depend on origin placement. Once he defined it he went on with an example of how a vectors magnitude is conserved in two different coordinate systems. So my question is what is the definition of a true vector?
Full Answer
True vector may refer to: A polar vector, one that is not a pseudovector (or axial vector). More formally, a true vector is a contravariant vector, see: Covariance and contravariance of vectors. True vector display, as opposed to a simulated or rasterized vector display. This disambiguation page lists articles associated with the title True vector.

Magnetic course is another term that is based on true course. True course bases its movement calculations on the plane’s location relative to true north. Since true north is based on the earth’s magnetic field, and the magnetic field can fluctuate, the true course today and the true course tomorrow may be different.
Depending on the reference direction the following terms are used: true course or true heading is expressed as angular distance from true North clockwise from 000° through 360°. magnetic course refers to magnetic north. How do you calculate ground speed?

True velocity can be defined as the resultant velocity at play in a real-life scenario. It is calculated after taking all the influencing factors into account.

Let r(t) be a differentiable vector valued function representing the position of a particle. Then the speed of the particle is the magnitude of the velocity vector. Speed=||v(t)||=||r′(t)||. r(t)=3ˆi+2ˆj+costˆk.
The apparent velocity is equal to the true velocity only when the refractor is parallel to the surface. If the refractor is dipping, the apparent velocity measured in the updip direction will be higher than the true velocity, and that measured in the downdip direction will be lower.
A velocity vector represents the rate of change of the position of an object. The magnitude of a velocity vector gives the speed of an object while the vector direction gives its direction. Velocity vectors can be added or subtracted according to the principles of vector addition. velocity vectors magnitude.
A vector is a specific quantity drawn as a line segment with an arrowhead at one end. It has an initial point, where it begins, and a terminal point, where it ends. A vector is defined by its magnitude, or the length of the line, and its direction, indicated by an arrowhead at the terminal point.
The resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together. If displacement vectors A, B, and C are added together, the result will be vector R.
Displacement is the vector difference between the ending and starting positions of an object. It may be very different from the distance the object has travelled along the way. Velocity is the rate at which displacement changes with time. It is a vector, too.
Distance is a scalar quantity and not a vector quantity as it has only magnitude. It means when object moves, its direction does not matter only magnitude of distance is considered.
10. The average acceleration vector: is defined as the rate at which the velocity changes. It is in the direction of the change in velocity Δv. The instantaneous acceleration is the limit of the average acceleration as Δt approaches zero.
Vector Quantity Definition The physical quantities for which both magnitude and direction are defined distinctly are known as vector quantities.
True course is a term that tells you what course an airplane is following across the ground. Airplanes are designed to calculate their true course using a sectional map and a navigation plotter.
Pilots are in great demand and learn an impressive amount of information that allows them to do their job. Learning aviation terms is an important part of flying a plane. Some terms are commonly used, so anyone who flies a plane for any amount of time will inevitably learn about true course vs true heading and some other terms.
Since true north is based on the earth’s magnetic field, and the magnetic field can fluctuate, the true course today and the true course tomorrow may be different. Magnetic course corrects for differences in the magnetic field. Magnetic heading is very similar.
Magnetic heading is your direction relative to magnetic north, read from your magnetic compass. True heading is your direction relative to true north, or the geographic north pole. The difference is due to the magnetic north pole and geographic north pole being hundreds of miles apart.
What’s up with Magnetic North vs True North? “ True north” is the northern axis of rotation of the Earth. It is the point where the lines of longitude converge on maps. “ Magnetic north” is the point on the Earth’s surface where its magnetic field points directly downwards.
You can determine the magnetic variation from a sectional map. True Course: The aircraft’s course over the ground relative to true north. True course is measured with a navigation plotter and a sectional map. True Heading: True course corrected for wind.
Most large aircraft use inertial reference units and flight management systems that complete calculations using True North and add magnetic variation values from tables to display information to pilots.
VOR degrees are magnetic, not true, so you can read your magnetic course for that location right from the VOR rose. Again, the difference between the true course you’ve drawn on your chart and the magnetic course that runs through the VOR rose is the magnetic variation.
Water is almost completely non-magnetic, so magnets work underwater the same as they do in air or in a vacuum. Magnets underwater work like they do above ground—if they find something they’re attracted to, the force between them pulls them together.
Heading is typically based on compass directions, so 0° (or 360°) indicates a direction toward true North, 90° indicates a direction toward true East, 180° is true South, and 270° is true West.
