Ok another one
dy/dx = 2y/1- x^4
sol: y = C|1+x/1-x|^1/2 e^arctanx
Very confusing this is how i start out:
=> |2y dy = | 1/1-x^4 dx
=> y^2 = 1/4 lnu
=> y^2 = 1/4 ln(1-x^4) +c
=> y = (1/4 ln(1-x^4)+c )^1/2
then im lost, and ive probably stuffed it up right from near the start. im not sure if i should be using integration by substitution when integrating the x side.
Help appreciated
