Answer:
(√1 - a²)
Step-by-step explanation:
cos(sin⁻¹ a) = cos x°
sin x° = sin (sin⁻¹ a) = a
as shown in the attached picture
sin x° = a/1 cos x° = (√1 - a²) / 1 = (√1 - a²)
In the limit
we're interested in the value that converges to as
gets closer to
. So in fact
.
In the given example, is factorized to reveal a common factor of
in the numerator and denominator. We have
if
, so
so we can simplify
and *remove* the discontinuity.
Then
