VII (5) (a) Prove the Cauchy-Schwarz inequality for vectors in R”: v•w |v||w| for all v, w ER. Also show that equality holds if and only if v = lw for some > 0. HINT: Assume, without loss of generality, that v, w # 0. Consider the non-negative function o(t) = \v – tw|2. Show that º attains a minimum at t = 6:12. Evaluate o at this point and use the fact that ¢ is non-negative to conclude. Address...
The following function computes by summing the Taylor series
expansion to n terms. Write a program to print a table of using both this function and
the exp() function from the math library, for x = 0 to 1 in steps
of 0.1. The program should ask the user what value of n to use.

Write a regular function (i.e. in a function .m file) to calculate the series expansion of cosine(x). The number of terms calculated in the series should be specified in the input list of the function. Write a separate function that determines when the series expansion begins to deviate by at least 10% from the true value of cosine(x) based on the number of terms calculated in the series expansion, n. For n = 1, 2, … 10, determine the values...
7. (a) Use the well known Maclaurin series expansion for the cosine function: f (x ) = cos x = 1 x? 2! + 4! х 6! + (-1)" (2n)! . * 8! 0 and a substitution to obtain the Maclaurin series expansion for g(x) = cos (x²). Express your formula using sigma notation. (b) Use the Term-by-Term Integration Theorem to obtain an infinite series which converges to: cos(x) dx . y = cos(x²) (c) Use the remainder theorem associated...
