Full solution

Q. Solve the differential equationdydx=ex8 \frac{d y}{d x}=-\frac{e^{x}}{8}
  1. Recognize Problem: Recognize the problem as an antiderivative problem.\newlineWe are asked to find the function y(x)y(x) whose derivative with respect to xx is given by ex8-\frac{e^{x}}{8}.
  2. Write Integral: Write down the integral to solve for yy. To find yy, we need to integrate the given function with respect to xx. So, we write the integral as: y=(ex8)dxy = \int \left(-\frac{e^{x}}{8}\right) dx
  3. Perform Integration: Perform the integration.\newlineThe integral of exe^x with respect to xx is exe^x, and since we have a constant coefficient of 18-\frac{1}{8}, we can pull it out of the integral. Thus, we get:\newliney=18exdxy = -\frac{1}{8} \int e^x dx\newliney=18ex+Cy = -\frac{1}{8} \cdot e^x + C\newlinewhere CC is the constant of integration.
  4. Write Final Answer: Write the final answer.\newlineThe antiderivative of the function dydx=ex8\frac{dy}{dx} = -\frac{e^{x}}{8} is y=18ex+Cy = -\frac{1}{8} \cdot e^{x} + C.
