Homework Statement
Solve and obtain an expression for x in terms of θ given ## (3+ cos 2θ) dx/dθ = x sin 2θ##
Homework Equations
The Attempt at a Solution
...##dx/x = ((sin 2θ)/(3+ cos 2θ))dθ## ,
let ##u = (3+cos 2θ)⇒ du/dθ= -2 sin 2θ##
thus
##∫dx/x = -1/2∫du/u ##...[/B]are my steps correct?i can solve from here
