Weima learns to program. My attempt to do the exercises in sicp. Tuesday, January 4, 2011. Sicp exercise 3.80. Exercise 3.80. A series RLC circuit consists of a resistor, a capacitor, and an inductor connected in series, as shown in figure 3.36. If R, L, and C are the resistance, inductance, and capacitance, then the relations between voltage (v) and current (i) for the three components are described by the equations. And the circuit connections dictate the relations. Figure 3.36: A series RLC circuit.

Weima learns to program. My attempt to do the exercises in sicp. Tuesday, January 4, 2011. Sicp exercise 3.77. Exercise 3.77. The integral procedure used above was analogous to the ` implicit' definition of the infinite stream of integers in section 3.5.2. Alternatively, we can give a definition of integral that is more like integers-starting-from (also in section 3.5.2):. Define (integral integrand initial-value dt). Define (add-streams s1 s2). Define (scale-stream stream factor). Define (solve f y0 dt).

Weima learns to program. My attempt to do the exercises in sicp. Monday, December 27, 2010. Sicp exercise 3.68. Exercise 3.68. Louis Reasoner thinks that building a stream of pairs from three parts is unnecessarily complicated. Instead of separating the pair (S0,T0) from the rest of the pairs in the first row, he proposes to work with the whole first row, as follows:. Define (pairs s t). Stream-map (lambda (x) (list (stream-car s) x). Pairs (stream-cdr s) (stream-cdr t) ). Maximum recursion depth exceeded.
