    Area under a curve

    but that has nothing to do with the stochastic model or probability model... i need a formula or set of steps not a tool...

    Area under a curve

    I have an exponential function graph that was given to me as a question i had to find the points and find three different ways of finding the area under the curve. I found an Empirical model (finding the formula and integrating from one point to another) I found a Finite Element model...

    Breaking into traffic at an intersection

    I was given a very open ended question stating... "How Long will it take to break into a line of traffic at a 'T' intersection" I need some sort of start like a theory that includes this kind of thing. We have been studying probability this term so i need something to do with a probabilty...

    Integration help

    yer you get (1/30)[(1/-142000)/(142000+30v)] now what?

    Integration help

    im only in grade 12.... i dont have the time to take a day off or read calulus texts... i just need some one to tel me what to do and how to integrate it

    Integration help

    if this is true: 1/30((142000+30v)/(142000+30v)-142000/(142000+30v)) how do i then integrate it?

    Integration help

    nah im only in grade 12 in australia... i just need som help integrating this so i can solve a "flight" plan of a particle with variable acceleration... if you can help me with this it would be great

    Integration (displacement or position)

    if you think you can do it without that transition... go for it... that's just how i interpreted the question

    Integration help

    1/30((142000+30v)/(142000+30v)-142000/(142000+30v)) like this? what does this achieve?

    Integration help

    Homework Statement the trouble is in the integration on the left side (go straight o my answer down the bottom of the page)... please help me... mg-u-kv=m*a where (all constant) m= mass= 3000 g=gravity=10 u=thrust=172000 k=30 v=velocity=variable a=acceleration=variable...

    Integration (Velocity to Displacement or Position)

    what i ended up with is (e^-t/100)/(-30/100) x e^(-1205.525/-100)/t - 142000/30t that is after integration... is that what you meant?

    Integration (Velocity to Displacement or Position)

    i have already tried that... it didnt seem to work... could you show it in latex? so i can see what im doin wrong?

    Integration (Velocity to Displacement or Position)

    please help me with the integration in the word document.

    Integration (terminal velocity)

    for question 4.) mg-kv^2-u=m*v(dv/ds) i got (using the constant values 1/0.06*ln(|142000+0.03v^2|)=-1/3000*S+c when S=0, v=1000 therefore c=200.921 -1/3000*S=1/0.06*ln(|142000+0.03v^2|)-200.921 when v=0, S=? therefore S=9583.88 m using this same method i need the others...
