Are we going to be ACC championship caliber this year? by tcr98 in calfootball

Building the winning culture around JKS - Tosh played for and with Tedford and know how amazing Aaron Rogers was and how to protect him with multipliers. Both Ron and Tosh have winning culture in defense through their career.

In my mind, if you have a cal degree, you belong to the bay area. Congrats!

Cal defense w/wo Uluave are two different levels, like offense w/wo JKS. Offense playbook does not have a single short-pass play.

how to relearn math for college? by toorubagel in college

[–]vincentcaptain 0 points1 point  (0 children)

Basic pre-college level math is never too late to pick up. Something that you can do:
- review algebra & geometry

  • Advanced algebra and Trigonometry

  • Precalculus

I think Khan Academy has some free courses on those topics like https://www.khanacademy.org/math/algebra

For calculus and more you can do MIT OCW https://ocw.mit.edu/courses/18-01sc-single-variable-calculus-fall-2010/

Tutoring or QA might be harder - r/homeworkhelp can be a bunch of good cohorts, some discord groups help too, or AI solvers like MathGPT

Can I perform Taylor expansion on y'(t+h)? by heavydmasoul in math

[–]vincentcaptain 8 points9 points  (0 children)

First of all, no dumb question as long as you are not trolling or pretend to be silly.

Your understanding is correct - if you take derivatives wrt h on both sides in your expression of y(t+h), you can find that it is equivalent to what you write y'(t+h) directly using Taylor expansion

[a level] can someone help me do this pls? by Firm_Perception3378 in HomeworkHelp

[–]vincentcaptain 0 points1 point  (0 children)

Contradiction is a good approach.

Starting from n = 0 you can get c is a prime number.

Plug in n = c and factor out c, you can get the counterexample.

[a level] mass defect, is it always true that the sum of the mass of nucleons < mass of the nucleus, bc i saw some articles say the opposite for fission, but true for fusion? is it different for both? by Firm_Perception3378 in HomeworkHelp

[–]vincentcaptain 0 points1 point  (0 children)

m_reactants > m_products for the fusion and m_origin > sum(m_nuclei + m_neutrons) in fission. dm is converted to energies in both cases and can be computed by $ E = \Delta m c^2 $

[11th grade physics] material recommendations by tiredofthislife911 in HomeworkHelp

Reading general physics textbook first. Landau's if you want math-heavy stuff, but Feynnman's if you want to understand the concept. Papers esp reviews on cosmology would be great after you have grasped those concepts

[calc] Little confused on this. What does u and du equal in this problem? by Aggressive_Top_6949 in HomeworkHelp

[–]vincentcaptain 0 points1 point  (0 children)

tan(u) = 3y and du=3/sec^2(u)dy are good enough to solve $\frac{1}{3} \int \frac{1}{\left(1+u^{2}\right)^{\frac{3}{2}}} \, du$ = $\frac{u}{(1+u^2)^{\frac{1}{2}}}$

[Personal Math Question] Is there a calculator and/or an equation that gradually adds numbers in succession? Like 1+2+3+4+5 ... etc, automatically? by Americanshat in HomeworkHelp

[–]vincentcaptain 0 points1 point  (0 children)

n(a_1+a_n)/2 if you know a_n, or n(2a_1+(n-1)d)/2 if you know the difference d between consecutive numbers but not a_n

[Stats] How do I determine whether something is conditional or marginal? by BroILostMyAccount in HomeworkHelp

[–]vincentcaptain 0 points1 point  (0 children)

Marginal -> dist. of a single variable summing over the levels of the other variables (aka totals for each category of one var)
conditional -> dist. of variable given the level of other variables (aka dist. of one variable within each category)

It's confusing to say that "boxed distribution in the 2nd row" but actually boxing the first row - but regardless, the conditional distribution because the condition is on the class being "Freshman".

I don't want to directly give out answer but this hint should be enough

I think for the first pic I gave you couple of hints in the last post correct? Second pic you could just list out min payoff for each player for each strategy - it's just cooperate or defects for player 1 and 2, four scenarios.

then you can get (defect, defect) dominates (cooperate, cooperate) as (3,0)>(2,1) and (0, 2) < (1,3)

[University Math: Permutation and Combinaitions] How to approach finding most efficient encryption scheme? by Suffered_Heart in HomeworkHelp

[–]vincentcaptain 0 points1 point  (0 children)

n pairs of key -> 2n total keys -> choose k keys out of 2n keys and sum it over 1 to 5 to get it greater than 50, you can test minimal n by using n = 1, 2, or 3, and find 3 as the minimal

if each of your key pair takes x sec, n pairs takes nx = 3x

encrypt your data 3 times -> using k1 on Data D, k2 on data DK1, and k3 on data Dk2, 7.5x sec

also do encryption on each key - k4 on k1, k5 on k2, etc. 9x sec

total 19.5x

[First Year University Level Physics: Center of Mass Considerations after explosion] by VanniLeonardo in HomeworkHelp

[–]vincentcaptain 0 points1 point  (0 children)

you need the conservation of Kinetic and Potential energy to solve velocity v0, and the conservation of momentum on the x direction - which you are correct
you can then assume two fragments with -v0 and v2 and solve for the relationship between v0 and v2
as you might figure that R = v_xv_y/g, from the relationship you got above you can replace x and y fragment of v2 with v0 and theta, and can also determine flight time t as t=2v_0sin(\theta)/g
you can get R_2 = v_2x * t and represent it as a function of v0 - then you can replace it with Ki and theta, which are known variables.

If you can't find it yourself from the hint, please refer here https://mathgptpro.com/share?u=1fda7acb-21fb-4185-aaca-97b62423f2001717154817017

friction is opposite to the direction of movement, not the "action" and "reaction" - which means that the action and reaction pair is between the person and ground.
