Question

find the integral of F.dr ,where F=ie^x +jx^2,and r=i t^2+j t^3, t: [0.2]

Answer 1

do you still need help with this?

Answer 2

yes

Answer 3

then why did you close it?
oh well, so \[\vec r=x(t)\hat i+y(t)\hat j\]so now what are x(t) and y(t)?

Answer 4

\[\int\limits_C\vec F\cdot d\vec r=\int_a^b\vec F(\vec r(t))\cdot\vec r'(t)dt\]

Answer 5

thanks,,,i got it now

Answer 6
