7. 8. 9. In definite practice the integrals are frequently mentioned not as 0 to x but as from a lower limit to a . ........limit corresponding to the area preferred. The............ ........ of the integrals can be revealed by the estimation method sketched to be equal to the area under the curve. The integrals exhibit that the area under the curve as displayed by the integral is in fact the antiderivative with the........ ............ .limits. 10. Make the trapezoids minute enough and they get somewhat. State whether the following statements are true or false: 11. 12. to rectangles. This estimation approach can be carried to superior correctness by making slighter and slighter trapezoids. The integral is scrutinized as the area produced by summing a finite number of rectangles of infinitely minute width.
