Question

tan 1 +tan2 degrees +...........tan 89 degrees is equal to

Answer 1

Answer:

tan1°+tan2°+....+tan89°=1

Step-by-step explanation:

as we know Tan90= not define

given,

tan1°+tan2°+......+tan89°

it can also written as,

(tan1°+tan89°)+(tan2°+tan88°)+....+tan45°=not define +1=1

I take tan45° at last because it is middle term tan1°+ tan89°/2=tan90°/2=tan45°
