Evaluate the line integral ∫_C F⋅dr, where F(x,y,z)=−4sin(x)i+3cos(y)j−4xzk and C is given by the vector function r(t)=t^6i−t^5j+t^4k , 0≤t≤1.
we are given
we can find dr
now, we can set up integral
now, we can solve it
now, we can solve each integrals and combine them
we can use u-subs
now, we can solve second integral
we can use u-subs
u=t^5
du=5t^4dt
we can plug back u
now, we can plug bounds
now, we can solve third integral
now, we can combine them
now, we can simplify it
and we get
