Based on the figure and the expression for {{MATH_257}}, select all the correct expressions for {{MATH_258}}. {{CMD_259}} Recall: {{MATH_260}}. {{CMD_261}} {{CMD_262}} {{CMD_263}} {{MATH_264}}{{CMD_265}} {{CMD_266}} {{MATH_267}}{{CMD_268}} {{CMD_269}}{{MATH_270}}{{CMD_271}} {{CMD_272}}{{MATH_273}}{{CMD_274}} {{CMD_275}}{{MATH_276}}{{CMD_277}} {{CMD_278}} {{CMD_279}} So, we can write {{MATH_280}} and call it a {{CMD_281}}differential{{CMD_282}} of {{MATH_283}} at {{MATH_284}}. Notice that we can define a differential at any point {{MATH_285}} of the domain of {{MATH_286}}, provided that {{MATH_287}} exists.
