This is a Pascal program that prompts the user to input two real numbers, and then calculates a value for variable c based on a mathematical formula that involves various functions and operations. The calculated value for c is then displayed on the screen.
Here's a breakdown of the program:
Program p5; {Program name}
var
a,b,c : real; {Variable declaration: a, b, and c are all real numbers}
begin
writeln ('Введіть 2 числа:'); {Prints the message "Введіть 2 числа:" (which means "Enter 2 numbers" in Ukrainian)}
readln (a,b); {Reads in two numbers from the user and stores them in a and b}
c := (exp(b)*sqrt(a+b) + 5*sin(3*a)/15 + abs(3*b-6*a) + abs(exp(4*a)-ln(6*b))/4*cos(5*b) - sqr(a) + 6);
{Calculates a value for c using various functions and operations}
writeln('c=',c:4:2); {Prints the value of c on the screen, with 4 digits before the decimal point and 2 digits after}
end. {End of the program}
The formula for calculating c is quite complex and involves several mathematical functions, including:
exp: Calculates the exponential of a number (i.e., e to the power of the number).
sqrt: Calculates the square root of a number.
sin: Calculates the sine of a number (in radians).
abs: Calculates the absolute value of a number.
ln: Calculates the natural logarithm of a number (i.e., the logarithm to the base e).
cos: Calculates the cosine of a number (in radians).
sqr: Calculates the square of a number.
Overall, the program is calculating a value for c based on a complicated mathematical formula, using the user's input values for a and b.
