Question

find F(t)xG(t)

F(t) = 2ti-5j+t^2
G(t)= (1-t)i+(1/t)k
compute the cross product

Answer 1

heres what i got (-5/t)i - (2/t - t^2(1-t))j +(5-5t)k

Answer 2

my j is wrong but i dont know why

Answer 3

checking...

Answer 4

is f(x) =...t^2 k?

Answer 5

-2/t isn't correct on <j> it should be - {(2t*1/t) - t^2(1-t) }

Answer 6

J hat

Answer 7

ie you wrote 2/t instead of 2 :)

Answer 8

you there?

Answer 9

agreed
