How do you find the area using the trapezoidal approximation method, given # sinx(dx) #, on the interval [0, pi] with n=10?
Follow the steps below
-Firstly:[sketch the function f(x)=sin(x) on interval
-secondly:[find the width=(b-a)/n ]
-Thirdly: write the parts of interval
the sketch of function after separate it by intervals
-Fourthly calculate the area by using the law:
