I recently posted 'want some confirmation' and it was in relation this question:
dy/dx = (5x^2)(cos^2(y)) for y(1) = 5*pi
i get y = arctan[ 5/3 (x^3 -1)]
however the answer states y = arctan[5/3 (x^3 -1)] + 5*pi...
I have no idea where that 5*pi is coming from hence it lead to the post earlier.
Thanks in advance,
