49Chapter 3: Inverse Kinematics for 2D Movement

That said, this book primarily focuses on a geometric approach to solving

inverse-kinematics equations, which is just one of many great methods for

developing the inverse kinematics of robotic systems. Another useful (and

fun) method uses a branch of math known as linear algebra, and I highly

recommend learning it. (However, in this book, we won't be discussing any

inverse kinematics based on linear algebra.)

Though the image on the left might look quite a bit different than the one on

the right (Figure

), it’s nothing more than a new perspective. If you’ve

ever experienced any sort of graphing ...
