Find  the  area  of the  region bounded  by the  curves y equals  the  inverse sine  of  x divided  by 4,  y  =  0, andx  = 4  obtained  by  integrating  with  respect  to  y.  your work must include  the  definite integral  and theantiderivative.

You're asking in the ap section, so i'll give the ap calculus-style answer. alternatively, you can find the vertex of the parabola and use the "y"-coordinate as the answer.

the maximum height can occur at a critical number, that is, a number  such that  .

the derivative of  can be calculated as follows:



find a value of  that is a zero of the derivative:


this is parabola that is opening downward; we can assume there is a maximum at  .

to find that maximum, calculate  .
