sin^(-1)(x) = x+y, so y = sin^(-1)(x) - x. From there you just take the derivative. (I'll give you a hint: sin^(-1)(x) is the same as saying 1/sin(x)).

OpenStudy (tkhunny):

What? \(\sin^{-1}(x) \ne \dfrac{1}{\sin(x)} = \csc(x)\)

OpenStudy (astrophysics):

You mean to take the inverse, do not confuse it with the exponent to the power of negative 1

OpenStudy (anonymous):

Crap, you're right. My bad. The rest of it is correct, though. Just ignore the parenthetical statement.

jimthompson5910 (jim_thompson5910):

An alternative is to use implicit differentiation \[\Large x = \sin(x+y)\] \[\Large \frac{d}{dx}[x] = \frac{d}{dx}[\sin(x+y)]\] \[\Large 1 = \cos(x+y)*\frac{d}{dx}[x+y]\] \[\Large 1 = \cos(x+y)*(1+y \ ')\] solve for `y'`

OpenStudy (astrophysics):

Nice one jim

OpenStudy (chris215):

i got 0

OpenStudy (astrophysics):

How?

OpenStudy (chris215):

wait no it 1-cos(x+y)/cos(x+y)
