    Calculating the definite integral using FTC pt 2

    My bad, I re-did it and got 2. I still get the anti derivative of 2x^(1/2).

    Calculating the definite integral using FTC pt 2

    Answering that problem I get the anti-derivative of 2x^(1/2). subtracting a from b I get 3.

    Calculating the definite integral using FTC pt 2

    I have ∫5^(1/2) * x^(-1/2). then get [10^(3/2)/3]*[2x^(1/2)]. Not sure what you mean by n value for this problem. My interval a,b is 1,4?

    Calculating the definite integral using FTC pt 2

    Homework Statement Sorry that I am not up on latex yet, but will describe the problem the best I can. On the interval of a=1 to b= 4 for X. ∫√5/√x. Homework Equations The Attempt at a Solution My text indicates the answer is 2√5. I have taken my anti derivative and plugged in b and...

    Taking physics and dealing with depression/anxiety

    When I have it its pretty bad, pretty much dysfunctional, its very frustrating. I've tried a couple times with meds in the past but it didnt work very well. They do and I am signed up, the wait is weeks long though.

    Taking physics and dealing with depression/anxiety

    I suffer from serious bouts of depression/anxiety that come and go for no obvious reason. I started physics this year and its hit me half way through the semester. I made a doc appointment to fix this and I am afraid it will hurt me academically if its not fixed and I won't be able to do awesome...

    Pulling fractional exponents out of an expression

    So from this I get F'(t)= t^-3/4 (3/4t^1/2 - 1/2)

    Pulling fractional exponents out of an expression

    Homework Statement Find critical numbers of the function: F(x)=t^3/4 - 2t^1/4 Derivative I got: F'(x)=3/4 t^-1/4 - 1/2 t^-3/4 Homework Equations The Attempt at a Solution I have found the derivative and I understand I must pull out a t in order to find critical numbers, and run across this...
