Would you need to multiply the top and bottom by (cos+1)? Hmm...
Edit: Nevermind. I don't know anything anymore lol.

Is the answer -1/2?
I think you have to use L'Hospitals Rule.
f(0) = (cosx-1)/(xsinx)
so the denominator is basically 0*0 or x*x at this point which is x^2
cosx-1 can be written as -1+cosx or -(1-cosx)
Then you apply the rule and do the derivative of top and bottom
the top becomes -sinx and the bottom is 2x
the x's cancel and become 1's therefore being -1/2?

Objects moving in two dimensions can be hard to track, unless you use calculus to handle the motion. If an object is moving so its X coordinate follows the equation X = 2t + 1 and its Y coordinate follows the equation Y = t2 + 2, where t is the time in seconds, what is the object’s two-dimensional speed at t = 2 seconds? How do you solve this problem?

Don't you just differentiate both the equations? So x = t and y = 2t. Plug in t = 2 and you get (2,4).
It's asking for speed so you do differentiate. Speed (not a vector) is just the positive value of velocity (vector). The first equation should provide distance. Differentiating it once will provide velocity and another time will output acceleration.

But the correct answer to the question was √20 feet per second

Ahhh, my bad forgot to mention. I found you the x and y values, but you need to do the pyrgahteka theorem to find the answer. 2^2 + 4^2 and square root the answer. Therefore, you come out with sq rt 20.
EDIT: My spelling is terrible and I can't remember the guy's name lol.

Thanks.
Do you also know how the extreme value theorem can be true if f(x) = x is continuous on every closed interval but has no minimum or maximum?
