Hello hello everyone... I have a problem that I've been trying to figure out for a couple of days now. Its a question off of an assignment, and I have been busting my balls(excuse my french) with no results. HELP would be GREATLY appreciated...lthis is the question at hand: xsin(y) + x^3 = tan^(-1)(y) the second part is an inverse I have to find the first and second derivative, critical values, points of inflection, intercept, in order to sketch it afterwards. I shall cross my fingers with the hope that I will find genius out there :D !!!
