write the value of tan15.tan60.tan70

1.	write the value of tan15.tan60.tan70
Answer» tan 15° × tan 60 ° × tan 75°cot (90 - 75)° × tan 60° × tan 75°cot 75° × tan 60° × tan 75°_1_ × tan 60° ×° tan 75°tan 75 tan 60° = √3 Please check the misprinted last angle is 75° not 70°. Note : value of tan 70° cannot be found analytically, but it's approximate value is tan(70°)=2.74747.

Answer»

tan 15° × tan 60 ° × tan 75°cot (90 - 75)° × tan 60° × tan 75°cot 75° × tan 60° × tan 75°_1_ × tan 60° ×° tan 75°tan 75

tan 60° = √3

Please check the misprinted last angle is 75° not 70°.

Note : value of tan 70° cannot be found analytically, but it's approximate value is

tan(70°)=2.74747.
