110The Limit of a Function
Find the limit: limx0(1xarcsinx1x3)\lim\limits_{x \to 0} \left( \frac{1}{x \cdot \arcsin x} - \frac{1}{x^3} \right).
210Integrals
Let f(x)=1xtarctan(t2)dtf(x) = \int_1^x t \cdot \arctan(t^2) dt. Find f(1)f'(1) and f(1)f''(1).
310Techniques of integration
Evaluate 0dx(x+4)x\int_0^{\infty} \frac{dx}{(x+4)\sqrt{x}}.
410Differential equations
Solve the differential equation:

y=(1+x)1+sec2xy' = (1+x)^{-1} + \sec^2 x, y(0)=1,y(0)=0y(0) = 1, y'(0) = 0.
512Infinite Series
For n=13nn!xn1\sum\limits_{n=1}^{\infty} \frac{3n}{n!} x^{n-1}, determine the interval of convergence and also find its sum.
612Applications of differentiation
Let f(x)=x4+ax3+bf(x) = x^4 + ax^3 + b, and have a local extreme value of 17-17 at x=3x = 3.
(a)

(b)
Is that local extreme value maximal or minimal?
(c)
Is there any inflection point of the graph of ff?
712Applications of differentiation
Two particles are free to move on the curves y=x2y = x^2 and xy=1x - y = 1, respectively. What are their positions when they are closest together?
812Applications of differentiation
Determine the values of aa and bb such that the ellipse x2a2+y2b2=1\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1 contains the circle (x1)2+y2=1(x-1)^2 + y^2 = 1 and has least area.
912Multiple integrals
Evaluate R(yxy+x)1/2dA\iint_R \left( \frac{y-x}{y+x} \right)^{1/2} dA, where RR is the trapezoid in the xyxy plane bounded by the lines x=0x = 0, y=xy = x, x+y=1x + y = 1 and x+y=2x + y = 2.
