    Undergrad Can you solve a Disk, Washer, Shell method problem without drawing a graph?

    Because sometimes I may not draw the graph perfectly and may miss which equation is suppose to be subtracted from the other. I had this happen before.

    Studying Inquisitive studying bad for short term success and good 4 long term?

    Im having a issue with studying physics. When I receive a HW problem I dive deep into the problem in a holistic way. I tend to start solving problems that are related to the HW problem but are not the HW problem itself. For instance, I received a pendulum problem and was asked to find its...

    Newton’s Principia of Mathematics

    I found a book that was translated, however I would like to know the math before I dive in. I read that it was synthetic geometry and some other geometry, maybe Euclidean?

    Newton’s Principia of Mathematics

    Summary:: What kind of geometry/Math do I need to understand to read this book? Hey people! I would like to know what kind of geometry and/or math would I need to understand this book. I skimmed through it( The translated version by Florian Cajori) and seen that it gets technical with shapes.

    High School Understanding about Sequences and Series

    Homework Statement:: Tell me if a sequence or series diverges or converges Relevant Equations:: Geometric series, Telescoping series, Sequences. If I have a sequence equation can I tell if it converges or diverges by taking its limit or plugging in numbers to see what it goes too? Also if I...

    Undergrad Why is the absolute value of sinx used in the integral of cotx?

    Why is there a absolute value sign on sinx? Does it have to do with the domain of cot x and sin x?

    Undergrad Question about Inverse Derivative Hyperbola function

    There are different ways of doing math. As long as you follow the logic you can solve the problem. I do math in a way that I understand. I figured out what I did wrong. I was squaring the y^2 value to early in the problem. I was suppose to do it at the end to eliminate the square root.

    Undergrad Question about Inverse Derivative Hyperbola function

    Im confused about a certain part of solving an equation. So I used the hyerbola formula to find the answer but I think I did the math wrong. X^2-y^2=c^2 X=1 Y= (2x^5-1)^2 I did the calculations as you can see in the picture but I know I messed up on the square root part. When you square one...

    Undergrad Is arcsec = 1 divided by arccos ? Arcsec = 1/arccos

    This youtube video teaches you how to put it in the calculator.

    Undergrad Is arcsec = 1 divided by arccos ? Arcsec = 1/arccos

    I think I know what I did wrong. I redid the problem and got the right answer. I just don’t understand how when you put values in the calculator for arccosx and arcsec(1/x) you get and error for one and a number for the other.

    Undergrad Is arcsec = 1 divided by arccos ? Arcsec = 1/arccos

    Its completely different. Not sure what I am doing wrong. Unless arccos(x) ≠arcsec(1/x) like I stated at the top right of the board.

    Undergrad Is arcsec = 1 divided by arccos ? Arcsec = 1/arccos

    What do you get when you put it in a calculator? I tried to resolve the problem but with arcsec(1/x) and got a different answer than the derivative of 1/arccosx

    Undergrad Is arcsec = 1 divided by arccos ? Arcsec = 1/arccos

    Yes the negative on top and the one at the bottom cancel. I just didn’t show it canceling. Thank you for the help.
