Question

the value of tan1°tan2°tan3°•••••••••••••tan89° is​

Answer 1

Step-by-step explanation:

tan1°tan2°tan3°.........tan89°

tan1°tan2°.......tan44°tan45°tan(90-44)°.......tan(90-2)°tan(90-1)°

tan1°tan2°.......tan44°tan45°Cot44°..............Cot2°Cot1°

(tan1°Cot1°)(tan2°Cot2°).......................(Cot44°Tan44°) × 1 ......( tan45=1)

1×1×1..........×1

= 1

So, answer is one

Hope it helps you buddy

Answer 2

Answer:

tan60°=√3

tan1°tan2°.....tan89°=0

tan60°=√3×0=0

some value of tan 1° to tan89° is 0

then tan1°tan2°....tan89°=0
