Use differentials to approximate {{MATH_332}}. {{CMD_333}} Set {{MATH_334}}. We want to know {{MATH_335}}. Since {{MATH_336}}, we set {{MATH_337}}. Setting {{MATH_338}}, we have {{ENV_339}} Here we see a plot of {{MATH_340}} with the differentials above marked: {{CMD_341}} {{ENV_342}} {{COMMENT_343}} {{CMD_344}} {{CMD_345}} Now we must compute {{MATH_346}}: {{ENV_347}} Hence {{MATH_348}}. {{CMD_349}} {{CMD_350}}
