Question

fine the value of tan1° tan2° tan3°............ tan89°

Answer 1

Hello !

______________________________________

Convert Tan into Cot

tan 1 . tan 2 . tan 3 ...................... tan87 .  tan 88 . tan 89

tan 1 . tan 2 . tan 3 ........  tan ( 90 - 3 ) . tan ( 90 - 2 ) . tan ( 90 - 1 )

∴ tan ( 90 - theta ) = Cot theta

tan 1 . tan 2 . tan 3 ......... Cot 3 . Cot 2 . Cot 1

Multiply like terms

tan 1 . Cot 1 . tan2 . Cot 2 . tan 3 . Cot 3..... tan 89 . Cot 89

1 * 1 * 1 * 1 * 1 * 1 ..................................*  1

1^{n} = 1
