One of the most common questions that flits across a math student’s mind is, “Why does this matter?” Understandably, it may be difficult to see at a glance how finding a solution to the derivative of an expression might directly correlate to one being able to tie their shoelaces.

Thank goodness for calculus. Admittedly, some of the concepts are tough, but along the way you begin to see its wicked practical applications. Rather than simply juggling numbers and variables, you are beginning to apply the mathematical concepts you have picked up along the way to solve real-world problems. Suddenly, math has a purpose! Huzzah!

Shmoop, a publisher of digital curriculum and online test prep, is proud to announce the launch of its new Calculus Guide. Here, students can learn that “dy is over dx.” (Or is it in denial? It does still keep dx’s photo in a frame on its desk…)

And there’s more:

Shmoop relates real-life situations to advanced calculus concepts, including derivatives, limits, and differential equations.

Hundreds of examples, exercises, and sample problems. The best way to learn is by example. Which is how Jack Osbourne got to be such a phenomenal singer.

3 quizzes per chapter. Students master the skills, train with Newton’s weapons, and climb towards that black belt of calculus.

Shmoop’s “In the Real World” section will fill students in on how calculus is used in STEM fields. These are not meadows where the tops of wildflowers have been chopped off.

Graphs galore to help visualize calculus terms and functions. Let these axes be students’ allies.
