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}}
