Consider the differential equation dy/dx = xy. Let y = f(x) be the function that satisfies the differential equation with initial condition f(1) = 1. Use Euler's Method, starting at x = 1 with a step size of .1, to approximate f(1.2).

Step-by-step explanation:

From the question we are told that

Initial condition

Generally equation for is given mathematically as

Therefore

Generally the approximation of the solution is mathematically given by

Generally the is mathematically given by

Generally the is mathematically given by

Generally the approximation to the solution

at

Therefore

y=x+9

?

step-by-step explanation:

it has to have an angle of 90 degrees
