Question

prove that,
tan `¹ b-c/1+bc +tan`¹ c-a/1+ca + tan`¹ a-b/1+ab=0​

Answer 1

Answer:

hlo❤

tan`¹ b-c/1+bc= tan`¹ b - tan`¹c

:. tan`¹ c-a/1+ca =tan`¹ c -tan`¹ a

and, tan`¹ a-b/ 1+ab = tan`¹a -tan`¹ b

:.tan`¹ b - tan`¹c + tan`¹c -tan`¹a +tan`¹ a -tan`¹b

=0(prove)

hope it's helpful ❤

${\huge{\purple{ answer :}}}$

tan`¹ b-c/1+bc= tan`¹ b - tan`¹c

tan`¹ c-a/1+ca =tan`¹ c -tan`¹ a

and, tan`¹ a-b/ 1+ab = tan`¹a -tan`¹ b

tan`¹ b - tan`¹c + tan`¹c -tan`¹a +tan`¹ a -tan`¹b

=0
