So y = cos x ⇒ x = cos-1(y).The sine function sin takes angle θ and gives the ratio opposite hypotenuse . ... Likewise cos-1 is called acos or arccos And tan-1 is called atan or arctan. Examples: arcsin(y) is the same as sin-1 (y) atan(θ) is the same as tan-1 (θ) etc. Graphs of Sine and Inverse Sine. Sine. Inverse Sine.What are the inverse trigonometric functions? arcsin ( x) , or sin − 1 ( x) , is the inverse of ... Answer link. sin (arccos (x)) = sqrt (1-x^2) From Pythagoras, we have: sin^2 theta + cos^2 theta = 1 If x in [-1, 1] and theta = arccos (x) then: theta in [0, pi] sin (theta) >= 0 Hence: sin (arccos (x)) = sin (theta) = sqrt (1 - cos^2 theta) = sqrt (1-x^2) Note we can use the non-negative square root since we have already established that sin ....
