i have heard all about extremely uneasy things about calculus... "it's a throat-chocking concept and so on" but, thank god that few people have also said things like "basic calculus is all you need and it isn't a big deal". i have heard few things about integration and differentiation and also read the topic of limits on mathisfun.com.... i would like to learn basic calculus and learn to apply them in any type question for exams or real life situaions...:)

Hi;

basic calculus is all you need

Welcome! Who said that? Need for what? For physics? Yep! For computer science? Nope!

learn to apply them in any type question for exams or real life situaions

That will take a bit longer. I have been trying for 86 years!

hi gourish

Welcome to the forum.

You've made the right decision by looking at the MIF pages. A good one to start with is:

http://www.mathsisfun.com/calculus/introduction.html

If you find something that is not quite clear, post on the forum and we'll try to help.

That is the way for all self taught people.

I like "Calculus Made Easy" but Martin needs to do a bit more renovation again. His methodology (Thompson's) is quite good but he doesn't cover the geometrical meaning of a derivative until much later. And I would really like to remove some of Liebniz's notation into f'. Also, as a guy pursuing a doctorate in physics, much more then basic calculus is required. Look at this problem for example:

An object with weight W is dragged along a horizontal plane by a force acting along a rope attached to the object. If the rope makes an angle θ with the plane, then the magnitude of the force is given by the following equation, where μ is a constant called the coefficient of friction.

F = (muW)/(mu sin(theta) + cos(theta))

(a) Find the rate of change of F with respect to θ. (Use mu for μ and theta for θ as necessary.)

(b) When is this rate of change equal to 0? (Use mu for μ and theta for θ as necessary.)

(c) If W = 40 lbs and μ = 0.6, draw the graph of F as a function of θ and use it to locate the value of θ for which dF / dθ = 0. (Round the answer to two decimal places).

Physics, analytical chemistry (which is heavily reliant on stats), biology and comp.sci all require basic calculus knowledge at the start. Later though, a through knowledge of calculus will be almost certainly required. Then again, don't think of calculus as an extremely difficult discipline. It is just a very abstract concept which may take some getting used to. The MIF tutorials on it are just great, but if you need some more visual help you should check out Sal's videos. Also, bobbym, you have been doing calculus since you were around 6?

No, problem solving since I was six.

I was always jumping ahead and doing things my own way. I hated the way they went over the same things again and again at school. My mind would wander or daydream about what I thought were more interesting problems.

I have the result, but I do not yet know how to get it.

That's true until you hit university. Until then, I was bored but I have to participate due to pressure.

Libraries were always my favorite place to be. I was on the reclusive side. Not necessarily a good thing.

A lot of pressure on you?

It is the notation that attracts a lot of people to it.

7/3, I for one was so excited about learning calculus was purely for the sake of learning. I had no interest in calculus whatsoever, at least not at the start. Later on as time progressed, I became much more attracted to calculus. And what I meant by pressure was the constant fear of not getting in to a top university, or not achieving a 100% average.

I knew it could solve problems that I wanted answers to. Algebra, can only do so much. And again, I loved the Sigma sign!

Hi gourish;

This might be oversimplified but it seems that for physics the number one operation is differentiation. You can learn that.

Take Maxwell's equations for example. And bobbym, I know a computer programmer who believes computer science requires no knowledge of maths greater then 6th-7th grade,

Maxwell? If you mean the programmer, it's a she and she is not very good. She does claim to code in every single language I have heard of, but I highly doubt it. However, I know other programmers who are quite decent and do not think math is too important either.

Depends on the type of programmer and what they are asked to do. Generally, programmers are better at math than mathematicians are at programming.
