Use MATLAB to find the 8 point DFT of x(n) = cos(2πmn/8) (m=3)
for 0 ≤ n ≤ 7.
Plot both x(n) and its DFT and explain your results. The "dct"
and "fft" functions in MATLAB may be useful. Please post MATLAB
code.
-Use implicit differentiation to find dy/dx where
x2y2 + x cos(y) = 6
-Use logarithmic differentiation to find the derivative of o(x)
= (cos(x))ln(x)
-Find the first and second derivatives of p(x) = 6
ln(x2+3x)
-A balloon is rising vertically at a constant speed of 5 ft/sec.
A boy is
cycling along a straight road at a speed of 15 ft/sec. When he
passes
under the balloon, it is 45 ft above him.How fast is the
distance between
the boy...
Given that Csc(x) = - 3 and Cos(x) < 0, find the exact
value of each of the trigonometric function of x.
Functions are: a. Sin(x) , b. Cos(x) , c. Tan(x) , d. Csc(x) ,
e. Sec(x) , f. Cot(x)
If S = 1-x/1! + x^2/2! - x^3/3! + .....
where n! means factorial(n) and x is a variable that will be
assigned.
Use matlab to compute S for x = 7 and n (number of terms) =
5. Write the value below as the one displayed when you
issue "format short" in matlab. Explain the process and result of
the question.
