Pasensya na po sa abala haha
 
?[0, pi/2](sin(x) - cos^2(x)sin(x)dx)

= ?[0, pi/2](sin(x)dx) - ?[0, pi/2](cos^2(x)sin(x)dx)


Looking only at the second integral
J = ?[0, pi/2](cos^2(x)sin(x)dx

substitution:
u = cosx
du = -sin(x)dx

J = ?[0, pi/2](-u^2)du

J = (-u^3)/3|[0, pi/2]

J = (-cos^3(x))/3|[0, pi/2]
 
Last na po. Pwede po bang paopen po ulit 😁 Salamat
