Question

express tan alpha in terms of sin alpha...​

Answer 1

the tangent of x is defined to be it's sine divided by its consine: tanx= sinx cos x

Answer 2

Answer:

sin α / root ( 1 - sin^2 α )

Step-by-step explanation:

tan α = sin α / cos α

Identity : -

sin^2 α + cos^2 α = 1

cos^2 α = 1 - sin^2 α

cos α = root ( 1 - sin^2 α )

sin α / cos α

= sin α / root ( 1 - sin^2 α )
