Question 1075821
<pre>
{{{"y'"}}}{{{""=""}}}{{{sin(x)tan(y)}}}

{{{(dy)/(dx)}}}{{{""=""}}}{{{sin(x)tan(y)}}}

{{{dy}}}{{{""=""}}}{{{sin(x)tan(y)dx}}}

Separate the variables.  Divide both sides by tan(y)

{{{dy}}}{{{""=""}}}{{{sin(x)tan(y)dx}}}

{{{dy/tan(y)}}}{{{""=""}}}{{{sin(x)dx}}}

{{{cot(y)dy}}}{{{""=""}}}{{{sin(x)dx}}}

{{{int(cot(y)dy)}}}{{{""=""}}}{{{int(sin(x)dx)}}}

I think you can finish from there. If not tell me in the
thank-you note form below and I'll get back to you
by email. (No charge ever).
