Okay, its the end of the school year, and I had a really bad science teacher... and he gave me a low grade... not failing, better, but still the lowest grade I have gotton ever. He is very hard to talk to and deal with. It is too late now to do anything, but I want to make sure it dosent happen again next year, kind of stay on friendly terms with them... how do I do that? AND i frogot to mention, HE IS UNFAIR, and I AM NOT disrespectful to him back.
thanks

We have a radar gun at home and we can measure the velocity of the baseball when it leaves a pitchers hand, or when it leaves the bat after contact. We can also roughly estimate the angle or trajectory of the ball. I am sure there are equations out there that involve takeoff velocity in conjunction with the angle of takeoff, and also air resistance equations. I'm hoping someone with the knowledge or info can help me out. Basically , want to know how far the ball will travel when I hit it 80miles per hour (ball of the bat speed) and I hit it at a 45 degree angle. Thanks...

I have to fix an essay I wrote and I'm having difficulty finding the information. Here are the specific questions I need to complete:
-Define what a tangent line is
-Explain why the derivative is the instantaneous rate of change and the secant is the average rate of change.
-Explain why velocity is the first derivative of displacement and why acceration is the second.
-Why does the derivative being zero yield a minimum or maximum?
-Finally, what is calculated by the definite integra if the function is negative for every value between points a and b?

I am a true math-phobe so this is not fun for me! Any help would be greatly appreciated! I have visited tons of websites, but they all have this assumption that the viewer has some basic understanding of calc- I have NONE!

Thanks!

I would like to know if it is POSSIBLE and, if so, how I would go about projecting a video image onto a car window from the outside of the car so the occupants can see the image. I have a car wash and would like to be able to project promotions onto the dashboard while people are waiting.

I understand that the image will probably not be very crisp and that outside light might be a factor, but I want to know if it is possible and how I might be able to do it.

Thank you,

Josh
