a) Sketch a function that has a positive first derivative for x < −5, a derivative of zero for −5 < x < 5 and a negative first derivative for x > 5. (b) Call this function f(x). On the...
The original equation is: cos(x^2y^2)/sin(x^2y^2)=2x I simplified it to cot(x^2y^2)=2 I used chain rule to get -csc^2u * du/dx and found du/dx= (2x^2yy'+2y^2x) new...
