Write a program to find the area under the curve y = f(x) between x = a and x = b, integrate y = f(x) between the limits of a and b. The area under a curve between two points can be found by doing a definite integral between the two points.
#include float start_point, /* GLOBAL VARIABLES */ end_point, total_area; int numtraps; main( ) { void input(void ); float find_area(float a,float b,int n); /* prototype */ print(“AREA UNDER A CURVE”); input( ); total_area = find_area(start_point, end_point, numtraps); printf(“TOTAL AREA = %f”, total_area); } void input(void ) { printf(“\n Enter lower limit:”); scanf(“%f”, &start_point); printf(“Enter upper limit:”); scanf(“%f”, &end_point); printf(“Enter number of trapezoids:”); scanf(“%d”, &numtraps); } float find_area(float a, float b, int n) { float base , lower, h1, h2; /* LOCAL VARIABLES */ float function_x(float x); /* prototype */ float trap_area(float h1,float h2,float base );/*prototype*/ base = (b-1)/n; lower = a; for (lower =a; lower <= b-base ; lower = lower + base ) { h1 = function_x(lower); h1 = function_x(lower + base ); total_area += trap_area(h1, h2, base ); } return (total_area); float trap_area(float height_1,float height_2,float base ) { float area; /* LOCAL VARIABLE */ area = 0.5 * (height_1 + height_2) * base ; return (area); } float function_x(float x) { /* F(X) = X * X + 1 */ return (x*x + 1); } Output AREA UNDER A CURVE Enter lower limit: 0 Enter upper limit: 3 Enter number of trapezoids: 30 TOTAL AREA = 12.005000 AREA UNDER A CURVE Enter lower limit: 0 Enter upper limit: 3 Enter number of trapezoids: 100 TOTAL AREA = 12.000438
Explain the Loop Statements in Computer Programming? 1. C gives you a choice of three kinds of loop, while, do while and for. 2. The while loop remain repeating an action until
The digital signal is one which only consists of two states i.e. logic '1' (+5 volts) and logic '0' (0 volts). Various electronic blocks use logic and these form the basis of a m
Rewrite the recursive bisection root finding function from lecture to be iterative (using a while loop). The function declaration should be root = bisectIter(f,a,b,tol). The input
y=2x-3?_(i=1)^(n+1)¦?i+2?
Problem: (a) (i) What is a structure? (ii) How does a structure differ from an array? (b) Declare a structure, called account, that will contain the following data me
how many types of loops are there and whay are they and what are its uses
No. it's not required The C++ language guarantees that delete p will do nothing if p is equivalent to NULL. As you might get the test backwards, and as most testing methodologie
payment system, in c++ only..just use the printf or scanf.please
C Program for FUNCTION OF MERGE #include conio.h> #include stdio.h> char cot(char a[],char b[]); void main() { char a[50],b[50]; clrscr()
Explain what are Unions? The Unions like as structures, contain members whose individual data types may perhaps differ from one another. Though the members that create a union
