Hello everyone I am hoping to get a little with a system. Here is the the system: dx = y dt dy = -y^2 - sin(x) dt I need to find all the equilibira and determine whether they are sinks, sources, etc... I need to sketch the x and y nullclines. Indicate the direction of the solution curve in any regions bounded by the nullcines. Lastly, sketch the entire phase plane. Thank you for the help in advance!
