Question

d

—(∫(x²–3x+1)dx)=

dt

Answer 1

When taking a derivative, it is important to note which variable to consider. In the example above, it is a derivative concerning the variable t. As such, the expression to be derived should contain the variable t, and if not, it is considered a constant. Above, we would be taking the derivative of a constant. Thus,

d/dt[ ∫(x²–3x+1)dx] = 0.
