Understanding Club Communication & Feedback

We've all been there: receiving an email from a club or organization that sparks an immediate reaction. This document explores different ways members might react and how to effectively communicate feedback, from initial thoughts to formal correspondence.

Immediate Member Reactions to Club News

Sometimes, the first reaction to club news can be a mix of emotions, even contradictory ones. Here's an example of an immediate, unfiltered response:

"I just received an email from the club. I can’t believe it! I just signed up, and I thought it was formal. If I had known, I would have chosen a different club. I don't understand why they didn't tell us earlier!"

"On the other hand, I’m so excited! I just

Derivadas

derivative rules

der(x^a) = a . x^a-1

der(a) = 0

(f+-g)' = f' + g'

(a.f)' = a .f'

(f/g)' = ((f'.g-g'.f)/g²)

der( ln(x) ) = 1/x

der( ln|x| ) = 1/x

der( e^x) = e^x

der( log(x) ) = 1/(x.ln(10))

der( log_a(x) ) = 1/(x.ln(a))

common limits

lim_x->cf(x) = ∞

lim_x->cg(x) = L

lim_x->c[f(x) +- g(x)] = ∞

lim_x->c[f(x) . g(x)] = ∞, L>0

lim_x->c[f(x) . g(x)] = - ∞, L<0

lim_x->∞(1 + k/x)^x = e^k

lim_x->∞[axⁿ] = ∞, 0

lim_x->0(1 +x)^1/x = e

Trigonometria

basic identities

tan(x) = sin(x)/cos(x)

cot(x) = cos(x)/sin(x)

sec(x) = 1/cos(x)

csc(x) = 1/sin(x)

pythagorean identities

sin(2x) = 2 sin(x)cos(x)

cos(2x) = 1 - 2.sin²(x)

tan(2x) = 2tan(x) / 1-tan²(x)

sin(x) | -1<= y <= 1 | arcsin(x) | - (π/2) <= y <= π/2

cos(x) | -1<= y <= 1 | arccos(
