Question

tan2Atan3A=1 find the value of A

Answer 1

Step-by-step explanation:

Given that tan2Atan3A = 1

=> tan2A = cot3A

we know that ,

we know that , tan ( 90 - A) = cot A

we know that , tan ( 90 - A) = cot Athen tan 2A = cot ( 90 - 2A )

so, cot ( 90 - 2A ) = cot 3A

so, cot ( 90 - 2A ) = cot 3A we get ,

so, cot ( 90 - 2A ) = cot 3A we get , 90 - 2A = 3A

so, cot ( 90 - 2A ) = cot 3A we get , 90 - 2A = 3A5A = 90

so, cot ( 90 - 2A ) = cot 3A we get , 90 - 2A = 3A5A = 90A = 18
