+    \begin{verse}
+        ^{G7}Is this x defined? ^{C7}Is f ^*{Gm7}con ^*{C7}ti ^*{Gm7}nu ^{C7}ous? \\
+        ^{F7}How do you ^{Cm7}find ^{F7}out? You can ^{B}use the ^*{Cm7} li^{B}mit ^*{F7} pro^{B}cess. \\
+        ^{Gm7}Approach from both sides, The ^{B7}left and the right and ^{Eb}meet. \\
+        ^{Cm7}Im a just a limit, ^{F7}defined analytically. Functions \\
+        ^*{H}continu ^{B}ous, ^{A}Theres no ^{B}holes, ^{H}No sharp ^{B}points, ^{A}Or asymp^{B}totes. \\
+        ^{Eb}Any way this ^{B}graph goes. ^{C#dim7}It is diffe^{F7}rentiable for me for ^{B}me.
+    \end{verse}
+    \begin{verse}
+        ^{B}All year, in ^{Gm}Calculus Weve ^{Cm}learned so many things \\
+        About which ^{Cm7}we are going to ^{F7}sing \\
+        ^{B}We can find derivatives And ^{Gm}integrals \\
+        And ^{Cm}the area en^{Eb}closed bet^{Eb}ween ^{Am7}two curves.
+    \end{verse}
+    \begin{verse}
+        ^{Eb}Y prime ^{H}oooh^{Cm}\_\_\_ Is the ^{Fm}derivative ^{E5+}of ^{Ab}y \\
+        Y ^{B7}equals x to the n, dy/^{Eb}dx \\
+        ^{B}Equals ^{Cm}n times ^{Abm}x To the ^{Eb}n-1. \\
+    \end{verse}
+    \begin{verse}
+        Other applications Of derivatives apply \\
+        If y is divided or multiplied \\
+        You use the quotient And product rules \\
+        And dont you forget To do the dance \\
+        Also oooh (dont forget the chain rule) \\
+        Before you are done, \\
+        You gotta remember to multiply by the chain \\
+    \end{verse}
+
+    (Instrumental solo)
+
+    \begin{verse}
+        I need to find the area under a curve \\
+        Integrate! Integrate!  You can use the integration \\
+        Raise exponent by one multiply the reciprocal \\
+        Plus a constant Plus a constant \\
+        Add a constant Add a constant \\
+        Add a constant labeled C \\
+        (Labeled C-ee-ee-ee-ee) \\
+        Im just a constant \\
+        Nobody loves me. \\
+        Hes just a constant \\
+        Might as well just call it C \\
+        Never forget to add the constant C \\
+        Can you find the area between f and g \\
+        In-te-grate f and then integrate g \\
+        (then subtract) \\
+        To revolve around the y-axis \\
+        (integrate) \\
+        outer radius squared minus inner radius squared \\
+        (multiplied) \\
+        multiplied by pi \\
+        (multiply) \\
+        Multiply the integral by pi! \\
+        Pi tastes real good with whipped cream! \\
+        Mama-Mia, Mama-Mia \\
+        Mama-Mia let me go. \\
+        Pre-calculus did not help me to prepare for Calculus, for Calculus, help me! \\
+    \end{verse}
+
+    (Interlude)
+
+    \begin{verse}
+        So you think you can find out the limit of y? \\
+        So you think youll find zero and have it defined \\
+        Oh baby cant define that point baby \\
+        Its undefined Goes to positive and negative infinity \\
+        Oooh. Oooh yeah, oooh yeah.  Differentiation \\
+        Anyone can see Any mere equation \\
+        It is differentiable for me. \\
+        (Any way this graph goes) \\
+    \end{verse}
