Title Description Use recursive method to find the value of N-order-de-polynomial, the recursive formula is n=0 pN (x) =1 n=1 pN (x) =xn>1 pN (x) = ((2n-1) *x* pN-1 (x)-(n-1) * pN-2 (x))/n results retain 2 decimal places.InputValues of N and X.Outputthe value of P N (x). Sam

conversion. 3. Inverse cotangent function conversion, the expression is as follows: Y=atan (x) *2/pi Second, premnmx, Tramnmx, Postmnmx, Mapminmax The PREMNMX function is used to normalized the input data or output data of the network, and the normalized data will be distributed within the [ -1,1] interval. The syntax format of the PREMNMX statement is: [Pn,minp,maxp,tn,mint,maxt]=premnmx (P,t), where p,t is the raw input and output data respectively

, the brightness of the bulb increases as well (before the transistor is saturated).For PNP transistors, the analytical method is similar, and the difference is that the current direction is exactly the opposite of NPN, so the arrow on the top of the emitter is reversed-turning into a forward direction. test transistor of the formula transistor tube type and pin identification is an electronic technology beginner's basic skills, in order to help readers quickly grasp the method of testing, the

the Horn clause in the first-level predicate logic. Only variables or constants can be used as the self-variable of the predicate, and functions cannot be used as the self-variable of the predicate. Datalog statements are composed of facts and rules. Like Prolog, Datalog statements can perform deductive reasoning on the knowledge base, that is, new facts can be obtained from known facts based on followed reasoning. A Datalog rule consists of the following three parts: (1) Rule header P (2) impl
