I t tried to post a drawing but it never went thru thats parts of hw

infraction????

TL;DR Summary: find how fast the distance is changing from 3rd base to a runer going to first base Mentor note: Thread has been moved from a technical math section, so is missing the homework template. A baseball diamond is a square with side 90 feet. A batter hits the ball and runs toward...

$$f'(x)=\displaystyle\lim_{h \to 0} \dfrac{\dfrac{(x+h)^2-1}{2(x+h)-3}-\dfrac{x^2-1}{2x-3}}{h}$$ my first inclination is to expand the numerator and combine the fractions

double \$\$ centers the latex which I don;t want other forums only require one $ wrap $ besides it didm"t render in the preview with double \$\$ anyway this we are supposed to solve by means of def of a derivative which can get quite involved $$f'( x)=\displaystyle\lim_{h \to 0} \dfrac{{f(x +...

$f(x)=\dfrac{x^2-1}{2x-3}$ ok I just don't see any preview so don't want to add more...

where is a good tikz forum ok from reading posts it seems that tikz code would come from users already proficient with it and then a rendered code from another program would upload a an image on PH, When MHB existed I got very valuable help on writing tikz code. And currently find it hard to...

Summary: want to post tikz here ok I really didn't know where to post this but can this forum render tikz I saw some other examples but don't know the setup here $\begin{tikzpicture} \draw[->] (-3,0) -- (4.2,0) node {$x$}; \draw[->] (0,-3) -- (0,4.2) node[above] {$y$}...

ok I would like that I don't know how to discern linear for non Linear from observation the yellow highlighted problems are ones I have done but want to do the 15-24 the link to the whole Boyce textbook in the OP if need. BTW I am retired so just doing this on my own might audit de at UHM...

it basically to solve just by observation like 2 order and linear no calculation is needed

ok it looks these are just observation problems but ? about linear non linear pare

double pound is not very collaborate with other latex editors this is the only forum I know of that asks that

here is an example I found from online ... but its probably beyond what my OP is asking for

ok I posted this a few years ago but replies said there was multiplication in it so I think its a mater of format ##\dfrac{\partial u^2}{\partial x\partial y}## is equivalent to ##u_{xy}## textbook

Mahalo every one
