Full solution

Q. Integrate.\newline cosxsinxcosx \frac{\cos x \sin x}{\cos x}
  1. Simplify integrand: Simplify the integrand cos(x)sin(x)/cos(x)\cos(x) \sin(x)/\cos(x). cos(x)sin(x)/cos(x)=sin(x)(cos(x)/cos(x))=sin(x)1=sin(x)\cos(x) \sin(x)/\cos(x) = \sin(x) \cdot (\cos(x)/\cos(x)) = \sin(x) \cdot 1 = \sin(x)
  2. Integrate simplified integrand: Integrate the simplified integrand. sin(x)dx=cos(x)+C\int \sin(x) \, dx = -\cos(x) + C, where CC is the constant of integration.
  3. Check for errors: Check the result for any mathematical errors. The integration of sin(x)\sin(x) is indeed cos(x)-\cos(x), and no mathematical errors are present in the calculation.
