Final answer:
To estimate the area under the graph of f(x) = sinx, divide the x-axis into small intervals, calculate areas of rectangles or trapezoids under the curve in each interval, and sum up these areas to estimate the total area.
Step-by-step explanation:
To estimate the area under the graph of f(x) = sinx, we can use numerical integration or approximate the area using geometric shapes.
One way to estimate the area is by dividing the x-axis into small intervals and calculating the areas of rectangles or trapezoids under the curve in each interval. Then, sum up these areas to estimate the total area.
Another way is to use a calculator or computer software that can perform numerical integration to get a more accurate estimation of the area.
