You have to be more clear, do you have to calculate the integral:
To start, write
pls what is the integral of 1/cotx+2
let me make it clearer guys;
the equation is dy/dx = cot(y+x)-1
solution is Cos(y+x)=ce-x
my problem is the process leading to the solution and was solved using variable saperable differencial equation
thanks for ur assistance.
