Can you provide a direct .jpg link to the image uploaded in my questions.I tried imgur.com but it is too slow to load and generate link.
@green In the above link , how they have got $s=-k^2s(2+\tan \theta)$

For a particle to execute $S,H,M,$ the direction of net force should be opposite to displacement.so if $\theta$ is direction of displacement it should be direction of net force as well.Now $Fx=F{net}\cos \theta$ and $Fy=F{net}\sin \theta$.Divide both equations.
