The mathematical horror show is upon us! Someone created a demonic summoning circle using calculus and trigonometry instead of ancient runes. Count 'em - there are indeed 8 mathematical formulas here, not 7 as the title suggests. The creator was probably too traumatized by derivatives to count properly. Each formula represents a different circle of mathematical hell - from the infinite series expansion of sin(x) to the definition of sine in terms of complex exponentials. This is what math professors see in their nightmares after grading finals where students write "I'll just use the formula" and then proceed to invent entirely new mathematics.
