Which of the following statements is/are INCORRECT? I. Beta measures a security's market risk, also known as systematic risk. II. SML is a graphical depiction of WACC model. III. If investors become more risk averse, the slope of SML will increase accordingly. IV. Other things being equal, a security's required rate of return doubles when its beta value doubles. V. Diversification will normally reduce the riskiness of a portfolio of securities. VI. Federal Reserve cuts an interest rate is considered...

Consider the following statements.
(i) Spring/mass systems and Series Circuit systems we covered
are examples of linear dynamical systems in which each mathematical
model is a second-order constant coefficient ODE along with initial
conditions at a specific time.

function
f (x) =

Consider the following statements.
(i) A Taylor series is a power series that gives the expansion
of a function around a point a. Convergence of such series
is fully understood by means of the ratio test.
(ii) We must rethink what we mean by solving

Consider the following statements.
(i) The Laplace Transform of
11tet2 cos(et2)
is well-defined for some values of s.
(ii) The Laplace Transform is an integral transform that turns
the problem of solving constant coefficient ODEs into an algebraic
problem. This transform is particularly useful when it comes to
studying problems arising in applications where the forcing
function in the ODE is piece-wise continuous but not necessarily
continuous, or when it comes to studying some Volterra equations
and integro-differential equations.

(1 point) We will determine whether the series n3 + 2n an - is convergent or divergent using the Limit Comparison Test (note that the Comparison Test is difficult to apply in this case). The given series has positive terms, which is a requirement for applying the Limit Comparison Test. First we must find an appropriate series bn for comparison (this series must also have positive terms). The most reasonable choice is ba - (choose something of the form 1/mp...

5. A matrix M is called idempotent if M2 = M. Which of the following statements must be true if M is an idempotent matrix? (i) M must be a square matrix. (ii) M must be either the zero matrix, or the identity matrix. (iii) M must be a invertible matrix. (iv) If M is an n xn matrix, then In - M must also be idempotent. (A) Only statements (i) and (ii) are true. (B) Only statements (i) and...

IGNORE (i)
(ii) The procedure of finding series solutions to a homogeneous
linear second-order ODEs could be accurately described as the
“method of undetermined series coefficients”.
(iii) The underlying idea behind the method of undetermined
coefficients is a conjecture about the form of a particular
solution that is motivated by the right-hand side of the equation.
The method of undetermined coefficients is limited to second-order
linear ODEs with constant coefficients and the right-hand side of
the ODE cannot be an...
