there are nearly (pi) x (10^7) seconds in one year. find the percentage error in this approximation, where percentage error is defined as abs value[ (assumed value - true value)/ true value] x 100% to find the true value I did: (365 days/yr) x (24 hours/1

Hello, I just wanted to verify if my work was good. Calculate the following integral by parts: ∫ upper limit is 1/5 and lower limit is 1/10. of 10sin^-1 (5x)dx so first I named the variables: u = 10 sin^-1 (5x) du = 50 / sqr(1-25x^2) dv = dx v = x so we

In the 1968 Olympic Games, University of Oregon jumper Dick Fosbury introduced a new technique of high jumping called the "Fosbury flop." It contributed to raising the world record by about 30 cm and is presently used by nearly every world-class jumper. In
