Answer 2

Explicación paso a paso:

[tg(a+b) - tgb] / tga[1 + tg(a+b)×tgb] = 1

(tga +tgb/1 - tga×tgb) - tgb = tga[1 + tg(a+b)×tgb]

(tga +tgb/1 - tga×tgb) - tgb = tga + tg(a+b)×tga×tgb

tga +tgb - tgb + tga×tgb²/1 - tga×tgb = tga + (tga+tgb/1 - tga×tgb)×tga×tgb

tga +tgb - tgb + tga×tgb²/1 - tga×tgb = [tga - tga²×tgb + (tga + tgb)×tga×tgb]/1 - tga×tgb

tga +tgb - tgb + tga×tgb² =tga - tga²×tgb + (tga + tgb)×tga×tgb

tga + tga×tgb² = tga - tga²tgb + tga²×tgb + tgb²tga

0 = 0
