Ethical Q. Split from Can Fire be explained ...
EudecioGabriel replied to EudecioGabriel's topic in Ethics
"Whether we should" ? Really? For a lot of things we don't wait the appointment of ethics or philosophy, but for building weapons we do? -
How do you explain the formula tan(20) = B/(A-C). In which Ax2 + Bxy + Cy2 + Dx + Ey + F = 0 ?

I mean't we shouldn't use science in any forms to develop violence. Oh... it would be cool something more emotional I guess with explain not killing other's while you're safe in your house. -
Find the area of 9 x^2 + 9y^2 + 72 x − 12 y + 103 = 0

I'm trying to use Integrals, what do you think? But this exercice is from Vectors and Analitic Geometry PDF, do you have another way of solving it? And I just can not find the center... can you help me? -
Hi! You should read about The Fundamental Theorem of Calculus, it's really easy believe me, you'll understand why the range of the Integral changed! It's not a eletrical understanding problem is just a few calculus basis . Good Look. And search for questions!! do some questions until you find one you have to make changes in the range of the integral! I lost one question about this last test , so I took 9 from 10 ( In Brazil we score in numbers, not in letters)

I don't think we really should use science to explain violence

Question: Sectioning a paraboloid for a plane perpendicular to it's axis and the three units of the vertice, we find an ellipsis of axis equal to 6 and 12 units. Write the equation of the paraboloid. I don't even know how to start! Thank you!

COOL!! THANK YOU GUYS! -
Integrate area between circle and a function
EudecioGabriel replied to EudecioGabriel's topic in Analysis and Calculus
Hello! I want to integrate the area between the function y(x)=x^2+y^2=1 and h(x)=|x|. Can you help me? Thank you!! -

Hi, I'm trying to understand why when a point belongs to a straight line the epura looks like this, in this case (A, B and C are the points) (R,T and (EF) are the lines) Sorry eventual english mistakes

How to calculate areas betweens functions?
EudecioGabriel replied to EudecioGabriel's topic in Mathematics
Ok. BUT ( integral of (x^2 + 5 ) - integral of (x^2 + 3 ) calculates the same way as (integral of (-x^2 +5) - integral of (-x^2+5) ? -
Do you want to be my professor? Did you actually wrote these lines of code for this post? This is very motivational I think

I'm using the book Calculus, 6th Edition (Stewart's Calculus Series), and I'm having some trouble to figure out why he calculates the difference between two integrals to find the area between then. It's ok for me to understand when the y values of both functions are positive. But when one of the y values in one of the functions is negative he uses the same formula (integral of A) - (integral of B) {A and B are two functions}! What about that rule that when the y value of the function is negative the integral is also negative?
