Hi, Can someone suggest a way to improve the lower rectangle method for area approximation...? I know one way is to increase the number of rectangles so if I put 100 instead of 5 rectangles i will get a better approximation. Another way it could be improved...?

So, I have this question, but I have no idea what constraint is and how to find a constraint for the length, height and width... and if i say the square wastage is x, then the width is 80-x but I don't know what the length would be with respect to x... , and how do we determine the dimensions..?

If f(x)=x^3+ax^2+bx has stationary points at: x= 2 and x= -4/3, find the value of a and b. In my homework, can't work out, Thanks in advance

I have no idea how to solve this equation, its in my homework... i know the formula to find the nth term(tn=ar^n-1) but don't know how to solve this: The difference between the first term and second term in a geometric sequence is 6.The difference between the second term and the third term is...
