left hand right hand ruleThe left hand rule is an approximate method for finding the area under the curve f(x) between the limits x=a and x = b which uses the formula:
\qquad \displaystyle \int_a^b f(x) \, dx = h(f(x_0) + f(x_1) + ... + f(x_{n-1}))
where x_0, x_1,... x_{n-1} \, are the values of x at the left hand end of n strips, each of width h
