<p>a) pertains to almost every type of problem</p>
<p>b) not really sure. </p>
<p>It depends on how good your math skills are and can also depend on the time lapsed between the time you learned the material and the time you do the problem.</p>
<p>Easy. Learn the material first, then you’ll know. :D</p>
<p>Otherwise, it’s really really hard to tell. Often the solutions to problems are only really obvious because you’ve seen those sorts of problems so many times before (in lectures, examples, &c). The first time those problems were solved, they required great ingenuity. Think about whoever first came up with adding and subtracting the same thing from the numerator of an expression. Or whoever first came up with dividing the area under a curve into a series of infinitesimally small rectangles…</p>
<p>Of course, if you haven’t learned the material already, you’re putting yourself in the same position as the people who first solved the problem. Except you’re probably much stupider.</p>
<p>rockermcr…the first post was by you right?
exactly! & i didn’t read it
I answered based on the thread
If you meant to say the thread???..because thats what its called…</p>
<p>IK’s post, which is the first post in this thread, has the number 1 on top of it. My post has the number 2 on top of it. Don’t you think that those numbers mean anything?</p>
<p><a href=“a”>quote</a> problems you don’t immediately know how to do - but you know how to solve easily once you learn the material</p>
<p>and
(b) problems you don’t immediately know how to do - and still wouldn’t know how to solve easily once you learn the relevant material
<p>Well, I would say that if you can’t do the problem after you’ve learned the material, then you really didn’t learn the material. Or I suppose it could just be that the problem has some trick or the solution is not immediately visible.</p>
<p>I really don’t know how to tell the difference between these two, since what you don’t know is unknown. You don’t know unknowns, so how can you possibly tell the difference between a known and an unknown?</p>
<p>Some problems are just initially overwhelming… for some people it’s hard to get over the fear of not knowing what a symbol represents or something like that.</p>
