We know that the net area of the region between a curve {{MATH_289}} and the {{MATH_290}}-axis
on {{MATH_291}} is given by
{{MATH_292}}
On the other hand, if we want to know the {{CMD_293}}geometric area{{CMD_294}},
meaning the ``actual'' area, we compute
{{MATH_295}}
{{CMD_296}}
The graph of a function {{MATH_297}} is given in the figure below.
{{CMD_298}}
{{ENV_299}}
{{CMD_300}}
{{CMD_301}}
{{CMD_302}} Express the geometric area of the region between the curve {{MATH_303}} and the {{MATH_304}}-axis on the interval {{MATH_305}} as a definite integral.
{{CMD_306}} Express the geometric area of the region between the curve {{MATH_307}} and the {{MATH_308}}-axis on the interval {{MATH_309}} in terms of definite integrals of {{MATH_310}}.
{{CMD_311}} Express the geometric area of the region between the curve {{MATH_312}} and the {{MATH_313}}-axis on the interval {{MATH_314}} in terms of areas {{MATH_315}}, {{MATH_316}}, {{MATH_317}} and {{MATH_318}}.
