Systems of equations with substitution Google Classroom Microsoft Teams You might need: Calculator

The substitution method is a technique for solving a system of equations. This article reviews the technique with multiple examples and some practice problems for you to try on your own.

Key takeaway: Sometimes we need to multiply or divide the entire integral by a constant, so we can achieve the appropriate form for u -substitution without changing the value of the integral.

This top one, you still didn't mess up by just setting u equal to sine of 5x, we just have to do an extra substitution in order to work it through all the way. And I was able to do this video despite …

When solving a system of equations using substitution, you can isolate one variable and substitute it with an expression from another equation. This will allow you to solve for one …

Solving for a variable first, then using substitution Sometimes using substitution is a little bit trickier. Here's another system of equations:

𝘶-substitution: indefinite integrals Google Classroom Microsoft Teams ∫ 3 x 2 (x 3 + 1) 6 d x =

In these series of videos (U-substitution) you introduce the treatment of the derivative operators (dx, du, etc) as fractions. You specify that they really are not, but treat them like that anyway.

Key point #1: Direct substitution is the go-to method. Use other methods only when this fails, otherwise you're probably doing more work than you need to be. For example, it would be …
