Why Learn Calculus?
In simplest terms calculus is just an extension of algebra and geometry. It’s not necessarily an entirely different subject, it just uses the tools of algebra to tackle new problems involving the rate of change for a curve whereas ordinary high school algebra and geometry do with straight lines and linear slopes. If you were to push a crate up an incline and that incline or straight you exert a constant force to move the crate up the slope since the slope is straight and unchanging. But if that’s slope were curved, you have to exert different levels of force at different points along the slope. As you reach deeper points on the curve you have to exert extra force to deal with the extra steepness. Therefore the force which we are measuring is changing depending on where you are. In this example, the amount of force on a Cartesian plane would represent y, and the distance covered would represent X. At any point, y would be dependent on X though X is constantly changing.
