(1 point) General Solution of a First Order Linear Differential Equation A first order linear differential equation is one that can be put in the form dy + P(2)y= Q(1) dz where P and Q are continuous functions on a given interval. This form is called the standard form and is readily solved by multiplying both sides of the equation by an integrating factor, I(2) = el P(z) da In this problem, we want to find the general solution of...

[10pts] Let's imagine that we have a first-order differential equation that is hard or impossible to solve. The general form is: df g(e) f(t)-he) dt where g(t) and h(t) are understood to be known. It turns out that any first order differential equation is relatively easy to solve using computational techniques. Specifically, starting from the definition of the derivative... df f(t+dt)-S(t) (dt small) dt dt we can rearrange the equation to become... www f(t+dt)-f(t)+dt-df (dt small) dt In other words,...
Which of the following is incorrect concerning Newton's First Law? I know that Newton's first law states an object at rest will remain at rest as long as the net force on the object is zero. I narrowed the questions down to three choices of the five: A) An object can not have a constant speed if the magnitude of net force is greater than zero. B) An object can not have a constant veloocity if the magnitude of net...
