The sign: Foamy or bubbly urine. What it means: You could have kidney disease. When your kidneyâs filtering units arenât working properly, that can lead to a build-up of protein in your urine. The protein then creates a foamy appearance when it hits the water in the toilet.
This gives us a point in the x1-x2 or phase plane that we can plot. Doing this for many values of t will then give us a sketch of what the solution will be doing in the phase plane. A sketch of a particular solution in the phase plane is called the trajectory of the solution.
We can then define the orientation of the aircraft by the amount of rotation of the parts of the aircraft along these principal axes. The yaw axis is perpendicular to the wings and lies in the plane of the aircraft centerline. A yaw motion is a side to side movement of the nose of the aircraft as shown in the animation.The yawing motion is being caused by the deflection of the rudder of this aircraft.The rudder is a hinged section at the rear of the vertical stabilizer.As described on the shape effects slide, changing the angle of deflection at the rear of an airfoil changes the amount of lift generated by the foil.e can then define the orientation of the aircraft by the amount of rotation of the parts of the aircraft along these principal axes.
