(a) You may assume that the Maclaurin series of cosh (r) is given by cosh(z) = 1+ 2 + 24 + higher degree terms. Suppose that the Maclaurin series of h(x) = * cosh(,I ) is given by h(x) = ark + bak+1 + cak+2 + higher degree terms. Enter the values of a, b, c and k below. be and K= Syntax advice: Your answers should be exact rational numbers, do not write them using decimal notation. For example: . 0.333333333 is only an approximation of 1/3
