Explanation:
A differential equation solver says the exact solution is ...
y = 5/2 -14e^(-2x) +1/2e^(-4x)
The y-values computed by Euler's method will be ...
y = ∆x·y' = 0.1(5 - e^(-4x) -2y)
The attached table performs these computations and compares the result. The "difference" is the approximate value minus the exact value. (When the step size is decreased by a factor of 10, the difference over the same interval is decreased by about that same factor.)
Answer:
True.
Explanation:
Analytical processing uses multi-levelaggregates, instead of record level access.
Answer:
A virtual privte network is a particular type of network that uses circuits that run over the Internet but that appears to the user to be a private network.
Answer:
Explained
Explanation:
Yes, I agree that digital signatures are the best way to protect the data in the date in question. A digital signature is mathematical technique used to validate the authenticity and integrity of a massage. Digital signature is far more inherent security. It is built to solve problems of tempering and impersonation of digital documents. It allows the authorized user to have authentic right, and the unauthorized person is denied access.
