    Solving the Limit of (lnx)^(1/(x-e)) as x Approaches e

    Aha! i see...so i just forgot to take the derivative of e's '1' exponent *smacks forehead* all this time and second guessing... Thank you very much, everyone! and sorry about the misunderstanding about 1/(x-e) as the exponent. still getting used to Latex. :D

    Solving the Limit of (lnx)^(1/(x-e)) as x Approaches e

    Hi, thanks for the reply. However, I don't see my mistake, it'd be great if you could point it out to me. I am following l'hopital's rule...so that's why I'm taking the derivative of the numerator and denominator separately instead of the product or quotient derivative rule.

    Solving the Limit of (lnx)^(1/(x-e)) as x Approaches e

    Heya! Here's a question that I CANNOT solve for the life of me. Thanks for any direction! Homework Statement lim (lnx)^{\frac{1}{x-e}} x\rightarrowe+ ^^ I'm not sure if Latext is clear, but x-e is an exponent to lnx Homework Equations So, I'm thinking L'hopital's rule in starting...

    Variable Problem for 2D Kinematics

    Thank you for your response. I was wondering if you could please elaborate on your post. My work is in my original post where i substituted time into the vot equation. Is this what you meant by equating time with the time that i have? (not quite sure what you mean) also, i have used that...

    Variable Problem for 2D Kinematics

    Here's another variable problem Homework Statement An extreme sportsman jumps from one cliff to another of width (w) by leaping horizontally by vo. With a height difference of h (where the starting cliff is higher) what is vo so he doesn't miss the cliff? (also, what is the direction of...

    Find the Length of a Curve with x=cos(t) and y=t+sin(t) from 0 to pi

    Oh, I see! It's matter of taking a further step and factoring out the \sqrt{2} from my initial integral. One question, how did you go from 1+cost to (1-cost^2)/(1-cost)? Thanks rockfreak. I'll try the question using that.

    Find the Length of a Curve with x=cos(t) and y=t+sin(t) from 0 to pi

    so, I substituted my two derivatives into the length equation, multiplied out my factors, and added sin(t)^2 with cos(t)^2 to get 1. Thus, sqrt of 1+1+2cos(t) is there a certain part of the integration that you see an error in?

    How Do You Calculate Volume Using Integrals for Disks with Varying Diameters?

    Thanks rohan for the posts. Sorry about the wordiness of the problem, but the question i have here on paper is even more convoluted. I now understand how the trig identities led to simplifying the integrals which allows for the antiderivative. The diagrams also helped me visualize the object...

    How Do You Calculate Volume Using Integrals for Disks with Varying Diameters?

    Hello! I have an integral problem here dealing volume. I think I have a good idea on how to get to the answer, but I'm stuck on finding the antiderivative. Here's my work! Thanx in advance to any help! Homework Statement There is a solid lying between planes perpendicular to the x-axis...
