Short Essay

We learned Calculus AP this semester, we learned introduction to calculus, the tangent problem and the velocity problem. What I know from introduction to calculus is that there are two parts of calculus and they attempt to solve two main problems respectively. Both parts have a foundation to them called limits. At same time, I know secant lines in The Tangent Problem class. Secant lines are lines between two points in shapes. We can use secant lines to find slop for an estimate, but we cannot find slop if we just know only one point on the line. Then, in the velocity problem. I know that velocity is rate of change of displacement, and speed is rate of change of distance. I also know equation of velocity equal displacement change divid time, speed equal distance change divide time, and Averge Velocity equal to total change in displacement divide total time.

Beside math, I also learned a lot of that are very important things in classes. I think the most important one is always looking for good way. Looking for good way may make you stay positive, give you confidence, which can let you do better job. Another one I think the most important is don't care of past. What happened in the past were already there, you can't change things is happened. Thus, we need to look forward, we can decide what will happen in future!
