This is the third course in the standard calculus sequence. In this course, we embark on an exciting journey beyond the boundaries of single-variable calculus to explore the intricacies of functions of multiple variables. Our focus will shift from the limitations of two-dimensional graphs to the dynamic landscapes of three dimensions and beyond. With multi-variable calculus, we equip ourselves with the tools to understand and analyze the world in a richer, more comprehensive way. Prepare to unlock the new dimensions!
