sin ^2 x+ cos ^2 x = 1

Step-by-step explanation:

sin^2 x - cos ^2 x sin ^2 x = sin ^4 x

Factor sin^2 x

sin ^2 x ( 1- cos ^2 x ) = sin ^4 x

Using the identity sin ^2 x+ cos ^2 x = 1 written as 1 -cos ^2 x = sin ^2 x

sin ^2 x ( sin^2 x ) = sin ^4 x

sin ^4 x = sin ^4 x

Tan (5π/6)
=tan (π-π/6)
=(tan π-tan (π/6))/(1+tan π tan π/6)
=-tan (π/6)
=-1/√3
=-√3/3
Hence the answer is: -√3/3
