plz short respsonse Describe the basic idea behind Euler’s Method. Compare this with the Improved Euler’s Method - in what way is it an improvement? Finally, compare both these methods with the Runge-Kutta method - what is the difference, and why does Runge-Kutta give more accurate results? Why would we choose to use one of the numerical methods, instead of solving the differential equation to obtain an exact answer? What is the characteristic equation? What is the connection between the...

1. For a special case, show that the Improved Euler’s Method may be referred to as the Trapezoid Rule. Support this claim by writing and solving an example problem using both methods. 2. The error associated with Euler's Method is proportional to step size. Euler's method will yield error-free prediction for a certain condition. What is the condition? Support the claim. 3. Use the Taylor Series to show that the Improved Euler’s Method and Midpoint Method have the same...

Use 4 steps of the Modiﬁed Euler’s method to solve the following diﬀerential equation to t = 2.6, given that y(0) = 1.1. In your working section, you must provide full working for the ﬁrst two steps. To make calculations easier, round the calculations at each step to four decimal places, and provide your ﬁnal answer with four decimal places. dy/ dt = 1.4sin(ty)

Biochemical Signaling i. Write out by hand the steps of the signal transduction pathway starting from binding of insulin to its receptor on a liver cell, leading to inhibition of glycogenolysis in that tissue. Include all steps in detail and hand write out this process. Look for hints as to the amount of detail on the Note Outlines with additional notes associated with Module 8. This also requires some review of module 5 on glycogen metabolism. Also remember insulin my...
