Webone independent variable, for example t in d2x dt2 = k m x often the indepent variable t is the time solution is function x(t) important for dynamical systems, population growth, control, … WebSubstituting here the value of r x we have just found, we get θ x = − y r2. You can find θ y in a similar way, starting from the equation x = rcosθ. Exercise 1. Find r y and θ y using the given hints. Differentiating once again, we can show that r xx = y2 r3, θ xx = 2xy r4, and find similar values for r yy, θ xx, and θ yy. This will ...
