# WELCOME

This is the homepage for MA 125: Calculus I

• First-day handout available here

• Solutions to the first exam are here.

• Solutions to the second exam are here.

• Solutions to the third exam are here.

• A proof by Mathematical Induction is here.

• Two Mathematica examples here. The first refers to problem 15 in section 2.2. The second shows the graph of sin(x)/x and computes a value close to x=0. Using Mathematica is very easy. Try typing in the (bold-face) line and hitting "return." Then modify and try again. Mathematica has on-line help features, if you need them. I strongly encourage you to experiment with this program, which is installed on the computers in the lab.

• Maria Agnesi's calculation of the point of inflection of a curve originally proposed by Fermat and Grandi. As a result of poor translation, the curve became widely known as the "Witch of Agnesi". The images are from the 1775 French edition of her famous treatise on calculus.
