From this you should see that the two versions of the Fundamental Theorem are very closely related. In reality, the two forms are {{CMD_48}}equivalent{{CMD_49}}, just differently stated. Hence people often simply call them both ``The Fundamental Theorem of Calculus.'' One way of thinking about the Second Fundamental Theorem of Calculus is: {{CMD_50}} {{ENV_51}} {{CMD_52}} This could be read as: {{CMD_53}}{{CMD_54}}{{CMD_55}}The {{CMD_56}} of a {{CMD_57}} is given by the {{CMD_58}}.{{CMD_59}}
