Consider the following algorithm for computing the area of a triangle with sides of length A, B, and C: S = (A+B+C) / 2 Area1(A,B,C) = sqrt(S(S-C)(S-B)(S-A)). A) Explain why this approach is unstable, and illustrate with an example. B) A student proposes the following less...

after connecting all the sets of coordinates of T with a line, the line isn't even straight.. can't find the slope..

im not sure what you mean by graphing them.. i put all the coordinates on a x/y graph, connected them with a line..

Hello guys, I have a question regarding mathematical logic that I'm stuck on. Here it is: T = { (5,9), (4,9), (5,7), (6,5), (5,5), (6,3), (7,1), (6,1), (5,1), (4,1), (3,1), (2,1), (1,1), (0,1) } F = { (5,4), (6,8 ), (2,11), (4,13), (8,1), (1,0) } 1) Make a simple open statement...

thanks.. i understand what you did, its just like linear ones but you add all the x-components and y-components... but for the examples i posted, the objects stick together after, so what will be the m1 and m2 (masses)? will there be two different masses, or will there just be one combined...

can you just show me how to do one?

i used that formula to solve linear questions.. but i don't know what to do for 2D ones.. can someone show me a step to step solution please? i am trying to get a clear picture of things but its so confusing..

hi.. I am having difficulty solving 2D momentum-collision questions.. i can do linear ones but somehow i don't know what to do for 2D ones.. can someone please help me? 1. A 3.2-kg hawk soaring at 20 m/s [N] collides with a 0.50-kg sparrow flying at 5.0 m/s [W]. If both the hawk and sparrow...
