Question

4) The value of tan1º. tan2º . tan3
tan89° =​

Answer 1

Answer:

Step-by-step explanation:

If (tan1°.tan2°.tan3°...........tan89°)

Then {tan1°.tan2°.tan3°............tan(90°-3°).tan(90°-2°). tan(90°-1°)}

Therefore (tan1°.tan2°.tan3°..........cot3°.cot2°.cot3°)

Therefore the answer of this question is 1
