In this unit, we go through the introduction to Calculus. Compare with other branches of math that are static, calculus is dynamic. We've learned that there are two parts of Calculus which are area problem (Integral calculus) and the tangent problem (Differential calculus). In the area problem, I learned A=lim An. A is the limit as n approaches of An and n is infinitive. In the tangent problem, I learned y=mx+c. m cannot be found because we only know one.
Besides, two more useful things that I learned in this class are staying positive and showing respect. Negative emotion always affects us when we try to keep going. We must，however，stay positive and never give up. What's more，respect is important in our daily life.
