This is the same solution displayed in the bottom-right ... We must calculate M4 = 4 f(xi)Δx = f(x1) + f(x2) + f(x3) + f(x4) Δx i = 1 , where x1, x2, x3, x4 represent the midpoints of four equal sub-intervals of [2, 10]. The period of the cos(x) cos ( x ) function is 2π 2 π so values will repeat every 2π 2 π radians in both directions. xsin. 1 x. = 0 by the Squeeze Theorem (Exercise 8.5). Thus, f is differentiable at x = 0 with f0(0) = 0. (c) f0(x) is discontinuous because cos. Cosx. 0 (cosx) = ln. = Sinh h. Cos cosh) sinh sinh. 和角公式. Cos(x+h) - Cosk h. = lame. COSX. Cosh -1. Sinh.

For example, let's consider f(x) = cos(x) (see Figure 1). The linear approximation of cos x near x0 = 0 approximates the graph of the cosine function by the ... F (x) = 0. using the function fsolve , which is based on the MINPACK ... cos(x) = -4. you first need to write a function to compute the value of the ...
