Inverse Tangent. y = tan-1x = arctan x is the inverse function to x = tan y with the restriction - < y < . In other words . y = tan-1 x is that angle y such that - < y < and tan y = x. Here is the derivative of y = sin-1x and the corresponding integral. Inverse Cotangent.

y = tan-1 x: y will be in Quadrant1 or Quadrant 4, use symmetry to get other answers. Know the domains and ranges of the inverse trig functions!! Some Common Basic Identities (You should know these): sin2 x + cos2 x = 1 (Corollaries: sin2 x = 1 - cos2 x, cos2 x = 1 - sin2 x)

Name________________________________
y = tan-1 x is the inverse of this restricted portion of the tangent function. y = tan x y = tan-1x. By the usual inverse relationship, the statements. y = tan-1x and x = tan y. are equivalent for y-values in the restricted domain and x-values in . This means that tan-1x can be thought of as the angle between whose tangent is x.

4tan-1(1/5) – tan-1(1/239) = (/4 (7) To prove (7), we could use this formula (8) but the coefficient of 4 in front of the inverse tangent function causes a problem. tan-1(x) - tan-1(y) = tan-1 (8) Therefore we must incorporate the double angle formula for tangent (9). tan 2x = (9)

Let . y= sin -1 x ∴ sin y = x . Think of . sin y = x 1 and represent this as a right-angled triangle, shown below.Find the missing side by using Pythagoras’ theorem and interpret results for . cos y and tan y . cos y = 1- x 2 . and . tan y = x 1- x 2 From ∴ sin y = x , dx dy = cos y . and using the result . cos y = 1- x 2 gives dx dy = 1 ...

The inverse of this restricted cosine function is defined by: y =cos -1 x , -1≤ x ≤1 and 0≤ y ≤ π use the convention of restricting the domain of tan x to – π 2 < x < π 2 , so the inverse function exists.
