Evaluate the line integral c y3 ds,<br> c.x = t3, y = t, 0 â‰¤ t â‰¤ 3

Temka [501]

$\displaystyle\int_{\mathcal C}y^3\,\mathrm dS=\int_{t=0}^{t=3}t^3\sqrt{1^2+(3t^2)^2}\,\mathrm dt=\int_0^3t^3\sqrt{1+9t^4}\,\mathrm dt$

Take $u=1+9t^4$ so that $\mathrm du=36t^3\,\mathrm dt$ . Then

$\displaystyle\int_{\mathcal C}y^3\,\mathrm dS=\frac1{36}\int_{u=1}^{u=730}\sqrt u\,\mathrm du=\frac{730^{3/2}-1}{54}$

Can someone please help me? i hope you can see this omg

Gemiola [76]

Step-by-step explanation:

length = (2x + 3) units

width = (x - 7) units

Area = 2( length × width)

Area = 2( (2x + 3) × (x - 7) )

Area = 2( 2x² - 14x + 3x - 21)

Area = 2 ( 2x² -11x - 21)

Area = 4x² - 22x - 42
