| you should just accept "c" for the antiderivative of 0, since that's how you write it if you're integrating a function. also, you need to check "accept one-character answers" on the quiz create page or else it won't work just to type in "x" for the antiderivative of one. ALSO, the derivative of 5/5x is just ln(x) because the fives cancel out. if you want to show outside and inside derivatives you could do 2x/(x^2) instead. finally, you spelled antiderivatives wrong in the title of your quiz. |
