In summary, to find oblique trajectories to y=x-1+c*e^-x, you can use the method of undetermined coefficients by assuming a general solution and solving for the coefficients. The constant c represents the initial condition and determines the position of the trajectory. Oblique trajectories cannot intersect and can be graphed by choosing different values of c. They are not always present in a function and only appear when there is a term in the form of c*e^-x.

How do I find the oblique trajectories to the following family of curves:

y = x-1 + c*e^-x

First find the differential equation to the family of curves given by differentiation wrt x and eliminating c. dy/dx will give slope of the curves at any point. If another curve's tangent makes an angle 'A', with this curve whose tangent at point of intersection is at an angle 'B', using tan formula:
tan(A+B)= (tanA+tanB)/(1-tanAtanB)

What are tanA and tanB to be substituted with next?
 

FAQ: Finding Oblique Trajectories to y=x-1+c*e^-x

How do you find oblique trajectories to y=x-1+c*e^-x?

To find oblique trajectories to y=x-1+c*e^-x, you can use the method of undetermined coefficients. This involves assuming a general solution in the form of y=Ax+B+c*e^-x and then substituting it into the original equation to solve for the coefficients A and B.

What is the significance of the constant c in the equation y=x-1+c*e^-x?

The constant c represents the initial condition or starting point of the trajectory. It determines the position of the trajectory in relation to the original curve y=x-1. Different values of c will result in different oblique trajectories.

Can oblique trajectories intersect?

No, oblique trajectories cannot intersect. They are parallel to each other and never cross paths. This is because they are determined by the same initial condition c, and therefore have the same slope at every point.

How do you graph oblique trajectories?

To graph oblique trajectories, you can plot points by choosing different values of c and solving for the corresponding y-values. You can also use a graphing calculator or software to plot the trajectories. It is important to label the trajectories with their corresponding values of c.

Are oblique trajectories always present in a function?

No, oblique trajectories are not always present in a function. They only appear when the function has a term in the form of c*e^-x, where c is a constant. If this term is not present, then there will be no oblique trajectories.
