I'm taking AP Calculus AB and I am failing with a D. Anyone who understands calculus really well, willing to tutor me? I got a 5/50 today on my test :| Thanks

@zarp29 cause a constant does not change, hence its rate of change is zero

Why is the derivative of a number 0?

You literally saves my... I'm studying on a distance course in a foreign language, teacher extremely unpedagogical the few times we see her. Same thing every time, I understand absolutely nothing after lessons, then I go home and watch a few videos that a guy on the other side of the planet has made and share with us for free and slowly I begin to grasp. It'not easy, it's a slow process, grades not the best but I do push through somehow, thanks to you!
