The u-substitution method was derived for integrals of this type. This method is named the u-substitution method because it involves substitution of expressions and the common substituted variable is u. Read U-Substitution for Integration | Formula, Steps & Examples Lesson ...
The formula for integration by parts is actually derived from the product rule for differentiation, but never mind that. You don't need to know that at this point. Just remember that integration by parts is for integrals of the form ∫f(x)g(x) dx, and typically NOT ∫f...

It can be noted that sometimes the integration by parts method will not give the solution of the integral, so in that case, we might need to apply the other methods. For example, we can apply the substitution method. Answer and Explanation: We ...
To solve the integration of the product of two functions, use the formula ∫udv=uv−∫vdu Insert context explanation here... Answer and Explanation: Given: ∫u(x)v′(x)dx=u(x)v(x)−∫u′(x)v(x)dx Rewrite the derivati...
