I dont have school all week long but i got tons of homework.... Okay so i started to do some derivative in my maths class and i have a couple of them to resolve.
Here is the one that i can't go pass step 2...
d/dx (3x^2-4) * d/dx (x^2-1)
okay so then i figured this out with the rules that he gave me..
d/dx (3x^2-4) * d/dx (x^2-1)
= d/dx (3x^2-4) * (x^2-1) + (3x^2-4) * d/dx (x^2-1) ---> where i got a derivate on both side that multiply a function, is it okay?
then i don't know if i can just multiply both polynom on each side and then add them together... But that you give me the same on both side?!
Also this one that i dont even know what to do !
d/dx ((x^2-4x) e^x) ???
