## Expressions for sin(arctan(x)) and cos(arctan(x)) that do not

sin(arccos(x)) = √1 −x2 Explanation: From Pythagoras, we have: sin2θ+ cos2θ = 1 If x ∈ [ − 1,1] and θ = arccos(x) then: θ ∈ [0,π] sin(θ) ≥ 0 Hence: sin(arccos(x)) = sin(θ) = √1

## Solve sin(arctan(x))

Then arctan( x 3) arctan ( x 3) is the angle between the positive x-axis and the ray beginning at the origin and passing through (1, x 3) ( 1, x 3). Therefore, sin(arctan( x 3)) sin ( arctan ( x 3)) is x 3
