Here are the 2 questions I am having issues with. I have no idea on number 1 Question1: A rectangular box without top is made from a metal sheet of 20x20 by removing a square from each corner and by folding the four side as in the following figure. Find the dimension of the square being removed that...
Checking my math on the rectangle problem: V(x)=x(20-2x)^2 =4x^3-80x^2+400x V'(x)=12^2-160x+400 4(x-10)(3x-10)=0 3x-10=0 3x=10 x=10/3 x=3.33 I also have another question as well: Find an equation of the tangent line of f(x) = sin^2(x) at 1/2 Here is what I got so far: sin'x(sinx)+(sinx)sin'x =cosxsi...
Good to know that my math, minus the the typo of leaving the x out, is good on the box question. I guess I will will restate the other two questions as we have gotten a bit far from the original. Question 1: Use lim n->inf (1+1/n) = e or its variation and logarithm to prove lim n->inf (1+x/n) = e^x ...
I will email him and find out if there is supposed to be an exponent on that. It makes no sense why everything I have looked up and what you have posted has it and yet his does not.
Any idea about the other question or would it be wise to actually put that in its own post?
Find an equation of the tangent line of f(x) = sin^2(x) at 1/2 I know the steps to solve this. Find the derivative, place derivative into the the original equation to find x (which I believe I can skip that part since I know x is 1/2), place X into derivative to find Y. Finally put into Y intercept ...
