    thank you so much. I didnt realize it was that easy lol.

    Domains of vector values functions

    Homework Statement r(t)- ln|t-1| i , e^t j , sqrt(t) k find the natural domains. this is a problem as an example in the book. Homework Equations It gives an answer of (-infinity,1) U (1,+infinity), (-infinity,+ininity) and [0, +infinity) and the intersection of these sets are [0,1)...

    How Do You Correctly Model Projectile Motion with Drag?

    Im working on the same problem. Do I plug in the initial values and integrate. or do i leave the initial velocity as v0 and then integrate?

    Integrating from 0 to 200 of 1/(14-(.0003x^2))

    I tried using partial fractions but I can't figure out how to factor the bottom expression

    Integrating from 0 to 200 of 1/(14-(.0003x^2))

    the function that i need to integrate is 1/(14-.0003X^2) I am pretty sure you use the Ln(14-.0003X^2)/(2(.0003x) but It doesn't work with 0 to 200

    Integrating from 0 to 200 of 1/(14-(.0003x^2))

    I can't figure it out.
  7. M

    Integrating from 0 to 200 of 1/(14-(.0003x^2))

    the answer should be 25.1

    Integrating from 0 to 200 of 1/(14-(.0003x^2))

    ok first i did ln(14-.0003x^2) divided by the derivative of the inside. but when i plug in the definite integral values i can't get the correct answer.

    Integrating from 0 to 200 of 1/(14-(.0003x^2))

    I can't figure out how to this integral. I keep coming up with the wrong answer. Can someone please show me a detailed solution?
