Solved Example of Line Integral:

The line integral curve calculator can determine the line integral for you easily but sometimes you have to do it manually. For that, we are giving you an example to let you know about each step of manual calculation,


An object moves from (-1,1) to (2,4) with the path r(t) = (t, t2), with the force F = <x sin y, y>. Calculate the work done.


The force in terms of t can be written as <t sin(t2), t2>, and evaluate r’(t) = <1,2t>and then the work is,

$$ \int_{-1}^{2} (t \; sin(t^2), t^2) . (1,2t) dt \;=\; \int_{-1}^{2} t\; sin(t^2) + 2t^3 dt \;=\; \frac{15}{2} + \frac{cos(1) - cos(4)}{2} $$

We can write,

$$ \int_{C} x\;sin\;y\;dx + \int_{C} y\;dy \;=\; \int_{-1}^{2} x\;sin(x^2) dx + \int_{1}^{4} y\;dy $$

$$ - \frac{cos(4)}{2} + \frac{cos(1)}{2} + \frac{16}{2} - \frac{1}{2} $$
