You'd automatically learn, some of the product in redox reaction so you can easily balance.
They are like math exercises, but i know most of the reactions which doesn't have a mechanism or where it came from is very boring, especially when there's not even any reasoning
@Mann can you star the plaintext version ,not via pin this message , but via the star on RHS. We don't want it to stick with the real one, we just want it to be starres so that when messages are removed after 14 days we can easily find it in all starred messages. and also because I cannot star it so someone else should, we can then star other interesting messaged so that it sinks
down and we don't see it but it remains in the star room and we can access it easily without trying all millions of messages
What is the maximum value of $x+y$ given that $x^2-4xy+4y^2+\sqrt{3x}+\sqrt{3y}-6=0$? $x,y$ are real numbers. Notice that it has terms $\sqrt{x}$ and $\sqrt{y}.$
I'm trying to show the following but I'm not very sure how to proceed. Could someone please explain to me how to approach and solve the following question?
Let $f : \Bbb R^2 → \Bbb R$ be differentiable such that $f(x, 2x) = 1$
and $f (−x, x) = 1 \; ∀x ∈ \Bbb R$. Using the Chain Rule, show t...
Hello everyone, I'm stuck while simplifying following trigonometric function $\dfrac{dy}{dx} = \dfrac{\sin (a+y)}{\cos y - x\cos(a+y)}$ help me out guys
Could someone please help me with the following question? I got stuck somewhere.
Given a function $u(t,x)$ satisfying the relationship:
$$
u_{tt} + au_t \ = \ c^2u_{xx} \qquad \text{ for some } a>0
$$
Show that the energy function $E(T)$ as defined below is a nonincreasing solution.
$$
E(t) \ ...
I want to make the following change:
$$u=x^2 - y^2 \quad v=xy$$ where my region is in the first quadrant bounded by:
$x^2-y^2 = 3 , \quad xy=1 , \quad x^2-xy-y^2 = 1 $ .
How can I prove this change of variables is legitimate ? (i.e., how can I prove this change is injective [one-to-one])
