+159 Sorry, I have no clue why the computer writes the equations this way but I'm pretty sure when there is a \ like for this exaple question question V=\frac{4}{3}\pi r^3 it is NOT a division sign I got confused on that for a sec so when it shows that before pi it doesn't mean divide by pi, just saying. So when it says \cos \big(2xy\big)=y thats just cos(2xy)=y, again I have no clue why the computer writes it that way I guess thats how computers read it.Sorry for making you go through the trouble, but THANK YOU VERY MUCH for lookin into this and helping out, I really appreciate it!
Given \cos \big(2xy\big)=y, find \frac{dy}{dx} in terms of x and y.
