what is the use of calculus in real world?
Hey! Another student here so don't count my answer on being comprehensive. In my experience, calculus has been useful for so many things, especially physics (which is indispensable for many types of engineering) and some statistical models (finance).
You could also add many applications in biology, including (among many examples) evolutionary theory and computational neuroscience
For example, calculate the velocity and acceleration , volumes , area...etc
it forms the basis for actuarial science.
I'm preparing for my first year PhD courses in economics by reviewing calculus--because there is a bunch of calculus involved in even the most basic economics principles.
Hey! what a question! I am using it in computer graphics, vectors, normals, dot and cross products everywhere, and discrete approximations of integrals on surfaces.
