What is the axis of symmetry of $$ y = (x 1)^2 1 $$ Axis of Symmetry Practice finding axis of symmetry from Standard Form Problem 6 What is the following parabola's axis of symmetry of $$ y =x^2 2x 3 $$ Answer Since this equation is in standard form, use the formula for standard form equation $$ x = \frac{ b}{ 2a} $$The eigenvalues λ± may be complex, but then they are complex conjugate If λ− 6= λ, we have two linearly independent solutions, and we write the general solution as y(x) = c1eλx c2eλ−x If λ− = λ, the solutions are not linearly independent, and we need another solution to span the solution space By variation of parameters (using the ansatz y2(x) = u(x)y1(x)), we findX = 1 25 7 10;

Hi Zach Since y^2 = x − 2 is a relation (has more than 1 yvalue for each xvalue) and not a function (which has a maximum of 1 yvalue for each xvalue), we need to split it into 2 separate functions and graph them together So the first one will be y 1 = √ (x − 2) and the second one is y 2 = −√ (x − 2) y = sqrt(Bx 1) We have xyy' xyy'= y^2 1 2xyy' = y^2 1 y/(y^2 1 )y' = 1/(2x) This is a First Order separable DE, so we can separate the variables to getA first order Differential Equation is Homogeneous when it can be in this form dy dx = F ( y x ) We can solve it using Separation of Variables but first we create a new variable v = y x v = y x which is also y = vx And dy dx = d (vx) dx = v dx dx x dv dx (by the Product Rule) Which can be simplified to dy dx = v x dv dx
