Almost every professional occupation out there requires about a Trig or Calculus level.
No however they need basic college algebra.
Im still taking Integral Calculus now, but for me, if you dont know Differential Calculus you will not know Integral Calculus, because Integral Calculus need Differential. So, as an answer to that question, ITS FAIR
So he can become a surgeon.
No, Just need to know your math and what you're doing.
Calculus is used a lot in business decisions. I am a Business Administration major. An examples is the break-even point in calculus. You need to know how to do this in business so you know how much of a product that you need to sell in order to cover your cost. Hope this helps some. +++ That is just one field, but Calculus is used in a huge range of scientific and engineering problems.
Algebra and calculus
I need calculus because I am not in a job where they put pictures on the cash register.
In order to solve problems using Calculus, you have to know Calculus.
I don't know the details about this particular student, but I would hazard a guess that he didn't know quite a few other things about calculus, either. In any case, if you don't know the fundamental theorem - at least, if you don't know how to apply it in practice - you'll have serious problems with many different problems - specifically when you need to do definite integrals.
You need to know calculus, as well as other advanced math topics, if you are going to work in engineering, physics or astronomy, chemistry, (sometimes) biology and generally any science. Otherwise, for many other areas, you really don't need calculus - although knowing the basics is interesting, for general culture.
Pre-calculus refers to concepts that need to be learned before, or as a prerequisite to studying calculus, so no. First one studies pre-calculus then elementary calculus.
Trigonometry isn't required to learn calculus, but it does help you to understand some of the concepts. Geometry, however, is usually required before taking a course in trigonometry.
