Area under a curve
Hey all.............
i need to find the area under a curve for an engineering problem i have, using a)rectangular and b)trapezoid methods....
for example: by sub dividing intervals [a,b]
if the sum of the areas for part a) are
∆w*{(a)^2+(a+ ∆w)^2 + (a +2*∆w)..........+(a+(n-1)*∆w)^2}
using 3 rectangles.....then rectangle #n for the function lets say y=x^2
any information on how to do this both ways would be greatly appreciated as i am really stuck and barely no where or how to begin.... thanks

You might find a for loop to be useful for such an application. Give it a shot and post any specific problems that you encounter.
