Question

tan1degree*tan2degree*tan3degree*.........*tan89degree

Answer 1

hey dear your answer is 1

because tan1 *tan89 like all pairs will be equal to 1 and only tan 45 will remain ..but tan45=1

Answer 2

Hey MATE!

tan1 canbe written as cot 89

so ,

the expression is changed as

(cot 89*)(cot 88*)............cot46* tan45* tan46*...............tan89*

all get cancelled ,

which remains tan45 = 1,

so the ans is 1.
