Full solution

Q. 1x+ssxf(t)=12 \frac{1}{x+s} \int_{-s}^{x} f(t)=\frac{1}{2}
  1. Understand the integral: Step 11: Understand the integral.\newlineWe need to evaluate the integral from s-s to xx of the function f(t)f(t) and then divide the result by (x+s)(x+s). The equation is given as 1x+ssxf(t)dt=12\frac{1}{x+s} \int_{-s}^{x}f(t) dt = \frac{1}{2}.
  2. Assume constant function: Step 22: Assume f(t)f(t) is a constant function.\newlineLet's assume f(t)=cf(t) = c, where cc is a constant. This assumption simplifies the integral to cc times the length of the interval from s-s to xx.
  3. Calculate integral: Step 33: Calculate the integral with the assumption.\newlineThe integral of a constant cc from s-s to xx is c(x(s))=c(x+s)c(x - (-s)) = c(x + s).
  4. Substitute integral result: Step 44: Substitute the integral result into the equation.\newlineSubstituting back into the equation, we get (1)/(x+s)c(x+s)=(1)/(2)(1)/(x+s) \cdot c(x + s) = (1)/(2). Simplifying, we find c(x+s)/(x+s)=1/2c(x + s)/(x + s) = 1/2, which simplifies to c=1/2c = 1/2.
  5. Check solution: Step 55: Check if the solution satisfies the original equation.\newlineSubstituting c=12c = \frac{1}{2} back into the integral, we get 1x+s12(x+s)=12\frac{1}{x+s} \cdot \frac{1}{2}(x + s) = \frac{1}{2}. This simplifies to 12=12\frac{1}{2} = \frac{1}{2}, which is true.
