1)How many integration methods were explained in class?
A)4
2
1
3
2)Which numerical method was implemented in class?
Trapezoidal rule
Secant
Regula falsi
Simpson rule
3)What is required in order to find the root of a function by numerical methods?
The function value at the start of the interval and the function value at the end of the interval must be of opposite signs
The function value at the start of the interval and the function value at the end of the interval must be of the same sign
The number of iterations must be very large
D)The epsilon value must be very small
4)Which method is NOT used to find th root of an equation?
A)Bisection
Regula falsi
Trapezoidal rule
D)Secant
5)Consider the class inheritance.
class B{
public:
B();
B(int nn);
void f();
void g();
private:
int n;
};
class D: public B
{
public:
D(int nn, float dd);
void h();
private:
double d;
};
How many private members does an object of class D have?
4
1

0
A)4
B)2
C)1
D)3
Explanation / Answer
1)
There are 6 ways to solve integration problems
I don’t all these topics are covered or not in your class
2)
Mostly in every class Trapezoidal rule and Simpson rule.
But I don’t which one implemented in your class
3) A
In order to find the root of a function by numerical methods, the function value at the start interval and the function value at the end of the interval must be of opposite signs.
4) C
Finding roots for non-linear equation using following methods:
Bisection
Newton – Raphson
Secant
False Position
Therefor Trapezoidal rule is not used.
5) C
Class D also contains the variable of Class B
In class D – one private member
In class B – one private member
