Understand the integral: Step 1: Understand the integral.We need to evaluate the integral from −s to x of the function f(t) and then divide the result by (x+s). The equation is given as x+s1∫−sxf(t)dt=21.
Assume constant function: Step 2: Assume f(t) is a constant function.Let's assume f(t)=c, where c is a constant. This assumption simplifies the integral to c times the length of the interval from −s to x.
Calculate integral: Step 3: Calculate the integral with the assumption.The integral of a constant c from −s to x is c(x−(−s))=c(x+s).
Substitute integral result: Step 4: Substitute the integral result into the equation.Substituting back into the equation, we get (1)/(x+s)⋅c(x+s)=(1)/(2). Simplifying, we find c(x+s)/(x+s)=1/2, which simplifies to c=1/2.
Check solution: Step 5: Check if the solution satisfies the original equation.Substituting c=21 back into the integral, we get x+s1⋅21(x+s)=21. This simplifies to 21=21, which is true.
