hi guys,
I´m struggling with this question on differential equations: dy/dx = (1+siny)/cosy.
I separated x and y, integrated and got to the point ln (1+siny)=x+const. but can´t find any way to express this equation in the form y= something.
can anyone help me please?
thanks a lot for any help!
Are you required to solve for y? Many first order differential equations are satisified by some f(x, y)= constant where y is NOT a function of x. Soroban's solution (using the principle arc cosine) gives one solution out of many. Adding multiples of will give other solutions.
