What is an Ordinary Differential Equation (ODE)?
Expert
It is an equation that involves an unknown function and its derivatives.
e.g.:
You should have learned how to classify ODEs by their order, degree, linearity, homogeneity, etc. (students are strongly advised to review their ?rst and 2nd year ODE courses).
Prove the law of iterated expectations for continuous random variables. 2. Prove that the bounds in Chebyshev's theorem cannot be improved upon. I.e., provide a distribution that satisfies the bounds exactly for k ≥1, show that it satisfies the bounds exactly, and draw its PDF. T
Who firstly discovered mathematical theory for random walks, that rediscovered later by Einstein?
Factorisation by Fermat's method: This method, dating from 1643, depends on a simple and standard algebraic identity. Fermat's observation is that if we wish to nd two factors of n, it is enough if we can express n as the difference of two squares.
Determine into which of the following 3 kinds (A), (B) and (C) the matrices (a) to (e) beneath can be categorized: Type (A): The matrix is in both reduced row-echelon form and row-echelon form. Type (B): The matrix
Select a dataset of your interest (preferably related to your company/job), containing one variable and atleast 100 data points. [Example: Annual profit figures of 100 companies for the last financial year]. Once you select the data, you should compute 4-5 summary sta
AB Department Store expects to generate the following sales figures for the next three months:
integral e^(-t)*e^(tz) t between 0 and infinity for Re(z)<1
Factorisation by trial division: The essential idea of factorisation by trial division is straightforward. Let n be a positive integer. We know that n is either prime or has a prime divisor less than or equal to √n. Therefore, if we divide n in
