the question states Use the Trapezoid Rule with n = 4 to approximate the length of the curve given parametrically by x = cos^3 t, y = sin^3 t where 0 ≤ t ≤ π/2 . Give your answer to four decimal... more

lim x=0(cotx-1/x)

f(x) = x2, (0,9)(x,y) smaller value(x,y) larger value

the moon, the acceleration due to gravity is one-sixth that of earth. That is22 gmoon = gearth /6 = (9.8 m/s )/6 = 1.63 m/s .What effect, if any, would this have on the period of a pendulum of... more

A ball that weighs 17.0 N is attached to the end of a 39.5 cm long string. The ball swings in a horizontal circle, so that the string makes an angle of 26.2° with the vertical, as shown in the... more

Hi, I get the idea that if something is larger than a diverging function, it also diverges and vice versa but my textbook gives me this problem ∫ 0 to infinity of dx/(1+x2) and the solution key... more

If exactly at 4.00 pm a car is on a hill and the direction of it's acceleration is uphill? Then describe the motion of the car at that time?

The student has access to the following measurement equipment: a spring scale, a meterstick, and a stopwatch. The student uses the spring scale to pull the cart starting from rest along a... more

A man starts walking north at 3 ft/s from a point P. Five minutes later a woman starts walking south at 4 ft/s from a point 500 ft due east of P. At what rate are the people moving apart 15 min... more

An enthusiastic kitten collides with a ball of string that is rolled towards it. The 0.5 kg kitten is travelling at 0.5 m s-1 due east before the collision and the 0.6 kg ball of string was... more
