    Need Help With Buffers: Test on Tuesday!

    Very Urgent: Need Help With Buffers! I have a test coming up on Tuesday and I have no idea how to do buffers, I don't understand what Value of the Ka we are suppose to use from the chart. I get the equation a little bit: [H+]= Ka x moles HB/moles of B- I am very lost please help!

    With New Problem due Wednsday

    I can't use any TRIGONOMETRY since we still didnt go over it in class, he wants a regular function.

    My professor said that there are a lot of such functions...

    With New Problem due Wednsday

    yes continuous and it has to be a NON-LINEAR function..and it has to follow the rule: f(x+1) = f(x) + 1

    With New Problem due Wednsday

    Please Help With New Problem...due Wednsday! The question is the following.. For all x f(x+1) = f(x)+1 a. f(x) has to be unbroken b. f(x) is non-linear I just have to come up with ANY example of f(x) for that to be true. So basically come up with any function which is unbroken and is not...

    How Do You Prove That Perpendicular Lines Have Negative Reciprocal Slopes?

    Well i can't use my definition all he said was his definition, and that's that they intersect and the slope of l2 is negative recipricol and that's it...we have to prove that

    How Do You Prove That Perpendicular Lines Have Negative Reciprocal Slopes?

    During class all he told us was to prove that if 1). L1 is perpendicular to L2 2). slope of L1 is M1 where M1 can't be 0 prove that slope of L2 is -1/M1...thats it and he said not to use anything we didn't learn, he didnt talk about rotating anything, or trignometry. =(

    How Do You Prove That Perpendicular Lines Have Negative Reciprocal Slopes?

    My professor doesn't want us to use trigonometry because we didn't learn that yet..and Dick, I am not sure I am allowed to use that as a proof..

    How Do You Prove That Perpendicular Lines Have Negative Reciprocal Slopes?

    Perpendicular is when two lines intersect to form 90 degree angles, slope is whether the line is moving up or down, and how much like the top value is the y and the bottom is the x.

    How Do You Prove That Perpendicular Lines Have Negative Reciprocal Slopes?

    Please Help With A Proof! If L1 is perpendicular to L2, prove that the slope of L2 is the negative reciprocal of the slope of L1.. PLEASE HELP ME!

    Find The Range And Inverse (please Help I Have Test Monday)

    I don't understand this at all... Find the Range and Inverse of f(x) = square root of [(8x^2 +1)/ (9-5x^2)] I am so confused please help!

    Proof That f(x) is 0 if Both Odd and Even

    Odd function is when f(-x) = -f(x) and even is if f(-x) = f(-x)

    Proof That f(x) is 0 if Both Odd and Even

    Homework Statement Prove that if f(x) is both odd and even (functions) then f(x) must be the constant function 0. Basically prove that no other function other than 0, can be both odd and even.
