Given all the morons and schizos on this board, I honestly can't tell if you're being a contrarian or are actually retarded.

what do

I have a few questions. Firstly, does an implicit derivative guarantee that the equation from which it was derived is not a function? Second, let's assume that I did not know, and could not find out, the equation that a particular derivative belongs to, but I did know that it wasn't a function. Is there some method to find out how many outputs there are in that equation for a given input? I ask because I was practicing applying Euler's method of numerical approximation on a derivative that happened to be implicit, and I only successfully approximated one of the points at the given input, when I knew for a fact that there were two points to be approximated there (it was a horizontal parabola). Sorry if this is basic and stupid but I'm a little confused.

Is it possible to stop being a brainlet?

I cant learn math in class?

Every other student always gets it and when they have to do an exercise on the blackboard they most of the time get it right.

But I am always the retard. People literally look at me like I am retarded when I get in a new class. They always think I am a brainlet but then at the end of the year I am always class best.

Why am I like that? Why do I always have to embarass myself?

What is the maximum scientifically possible mental/physical suffering that a human bean can experience and why is it being a brainlet?

will crispr fix my brainlet genes and give me a chance to experience life with an acceptable iq?

Please help me understand the use of calculus 1 linear approximation. I understand that, as Δx→0 , dy → Δy. I've looked at the graphical representation of this as well. What I don't understand is why I am using "nearby x values" to approximate f(x). I can see that it is true that the approximations get better and better but I don't really understand how this is useful to me.

At first, I thought that the idea was to simplify complicated functions to simpler linear equations using the tangent line and then evaluating that at the desired x value, producing the (y) output for both the line and the more difficult original equation (since both graphs cross that point) but then it occurred to me that doing this isn't necessarily any easier than just solving the original function because, to find the equation of the tangent line via the point slope formula, you need to be able to evaluate the derivative function at the given (x) in order to find the slope, and this calculation isn't necessarily any easier than the initial difficult problem that I was trying to simplify. For example, If I wanted evaluate f(x) = sin(x) at x = 1.29 , I couldn't do that without a calculator. However, theoretically, I could find the exact answer if I knew the equation of the tangent line to the curve there. The only problem is that would require finding the slope, which would require evaluating the derivative function f'(x) = cos(x) at x = 0.29 , which I also can't do without a calculator.

So what am I talking about? I honestly don't know. I don't know what I'm doing and I'm pretty confused. What is the use of linear approximation?

EE is boring. Why is everything boring. I don't want to apply for any internships because I don't actually care about this major. And I am too autistic to work with people. All I have going for me is my GPA but that won't stop me from being jobless when I graduate.
