You shall replace my calculator

Here's what I got as to why I can't be used as your calculator: Point 1: Different classes I may be able to help you in your math homework but I am sure not gonna be able to help you on a test or during class. We have different schedules, therefore, I can't really BE your calculator. Your calculator can be with you anywhere at anytime. I can't because I'm a simple human who has a life and needs to learn too. Point 2: Hindrance Trying to help you hinders me. Using the double effect, I get held back trying to explain and do all of these mathematical calculations for you. In order for me to explain things, I have to take up time. Time spent = less time available to continue excelling. Therefore, in time, I would fall behind and be at the same or even a lower level than the class. Point 3: I'm not infallible and I have limited capabilities I'm only a HUMAN! Humans are susceptible to mistakes and I am no exception. I can make a mistake here and there resulting in a wrong answer. I can't solve 67*54 without making some sort of a mathematical calculation error. Also, my mind is limited. I can't figure out what the sin or cosine of a number instantly. It takes time and even if it does take time, I don't have the time to figure it out. You're better off using a calculator for that because its a lot quicker. Quick note that I use a calculator too. So, since I use one myself, you really can't depend on just me to solve an equation. Point 4: Dependency If I was to help you, you'd depend on me too much. Dependency is not helpful in the slightest bit. You'll get lazy and just ask me to solve the problem and you'll be done with it. Yet you won't learn a thing. And remember that I can't be with you at all times so if you need to figure out a problem in that time, you're basically unable to solve it because you're too dependent on my skills. Onto your case: Although I admit I did memorize up to 1000 place of pi, that was only one feat. I have limits (going back to my 3rd point). I can't possibly remember everything mathematics based. Your first point falls. Same goes for your second point. My knowledge has limits. You stated that my mathematical knowledge is only advanced. It doesn't mean that there's no end to it. My mind is like any other mind. It has limits such as memorizing every SINGLE value for the sine, cosine, tangent, and the inverses of them of any angle. That's a lot of values. My mind can't possibly take all of that info and memorize it. Not even the best memorizer can hold all that info. Your 3rd point is useless. Anyone can draw graphs and label it. That means that just cause I can draw a graph, I can be used as your calculator. Then in that case, anyone can be your calculator just because they know how to draw a graph. Your fourth point provides a lot of evidence but that all involves work and if you've seen me, I'm lazy when it comes to that much work and I don't have the time to do all that. It's easier to just input all that into the calculator. It just takes a few pushes of a few buttons in order to find the trig values of any angle. It seems more logical to use the calculator. I'm not answering the pro's question because my average doesn't matter in this debate. My points sustain the fact that my intelligence has no relevance on the other fact that I can still make mistakes and be off on my calculations as aforesaid. So therefore, I urge a con vote.
