and I solve it using ode78 [t, R, te, Re, ie] = ode78(@odefun, tspan, r0, options) thus obtaining R(t). I want to solve the same equation but instead for the derivative (I want to get an array of dRdt and it's corresponding t). How should I go about that? Thank ...
To find the nth derivative, find the first few derivatives to identify the pattern. Apply the usual rules of differentiation to a function, then find each successive derivative to arrive at the nth. Example 1: Find the nth derivative of f(x) = xn Since this function has exponents, use ...

The most important consideration here is the order of the shape functions used for your dependent variables. If you, for example, would use linear shape functions, the second derivative is =0 by definition. But even with quadratic shape functions, the prediction of second deriv...
So let's actually do an example. Let's calculate the derivative of e^x from x= -1 to x=1. We're going to use the fundamental theorem of calculus, which says that I need to know the anti-derivative of e^x and evaluate it from -1 to 1. That anti-derivative is just e^x, bec...
Take the derivative of x1000 for example. Attempting to solve (x + h)1000 would be a time-consuming chore, so here we will use the Power Rule. Step 1: Find “n”, which is the exponent. For this problem, n is equal to 1000. Step 2: Substitute the value “n” into the front ...
What you should not do is drift along passively, assuming the problem will solve itself. You need to take action. But there is no systematic procedure you can follow. When you read biographies of people who’ve done great work, it’s remarkable how much luck is involved. They discover ...
The Fundamental Theorem of Calculus, Part 1: If f is continuous on {a, b}, then the function g defined by g(x) = \int_a^x f(t)dt , a \leq x \leq b is an antiderivative of f Use the second fundamental theorem of calculus to create an anti-derivative for ln (x) such that...
Answer to: Explain how to solve equations that involve the quotient of two functions as the ones given below: 1) f(x)/g(x) = 5 2) f(x)/g(x) = -5...
