If anyone can guide me on the following problems it would be great. Thanks!

1)A function f has a MacLaurin given by: (x^5)/2! + (x^6)/3!+...+[x^(n+4)]/ (n+1)!+..
what is the expression for f(x)?

2) The graph of function represented by MacLaurin 1 - x + (x^2)/2!-(x^3)/3!+...+[(( -1)^n)*x^n]/n!+... intersects the graph of y=2x^3 at x=?

3) When using e^x = 1+ x+(x^2)/2 to estimate sqrt(e), the Lagrange remainder is no greater than _____?

4) if the sum of [b(subscript n)]*x^n from n=0 to infitity is a tyalor seires the converges to f(x) for all real x, what is f'(1)?

5) What is the interval of convergence of the Taylor Series
f(x)= the sumer of [[(-1)^(k+1)]*(2x-1)^k]/k from (k=1) to infinity = (2x-1) - [(2x-1)^2]/2 + [(2x-1)^3]/3...on its interval of convergence

I know Edwin Hubble did not get it wrong, and I understand that it is space which expands, not matter, and light is stretched i.e redshift etc, but I can't visualise these galactic superclusters if everything is supposed to be receding and so fast too. Help!

An assignment question that I don't really understand, any help would be great. During the night, a planet rises above the horizon, travels across the sky and sets below the
horizon. In which direction would you have to look to observe the planet when it is highest in
the sky? Would an observer in the southern hemisphere look in the same direction?

I am doing an experiment write-up for an experiment involving the investigation in to how pH effects the rate of a reaction catalysed by the enzyme trypsin. I can't think of any safety measures except: always remain standing, wear safety spectacles, don't keep glass or substances near edge of table. I need more!

1.) A horizontal and a vertical force combine to give a resultant force of 10 N acts in a direction 40 degress above the horizontal. Find the magnitude of the horizontal and vertical force.

ans: Fh=7.7 N Fv= 6.4 N

2.) A sailboat cannot sail directly toward the wind but must "tack" back and forth at a certain angle with respect to the direction from which the wind is blowing. Which sailboat has the greater component of velocity to windward, the Alpha whose velocity is 5.0 km/h at and angle of 40 degrees away from the wind, or the Beta, whose velocity is 6.0 km/h at an angle of 50 degrees away from the wind?

ans:alpha= 3.83 km/h beta= 3.86 km/h

Solve x^3 + 2x^2 -13x +10 = 0

I know that there needs to be 3 values for x however, 2 are not real (x crosses at only 1 point around -1 and -.8)

Should I use the quadratic formula, sythetic division, or the rational zero test.

Please help and solve
