Evaluate the line integral c y3 ds,<br> c.x = t3, y = t, 0 ≤ t ≤ 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}

Write 6(x – 5)4 + 4(x – 5)2 + 6 = 0 in the form of a quadratic by using substitution.
pogonyaev

We are given the equation:

6(x-5)^{4}+4(x-5)^{2}+6=0..........(1)

Now we have to write it in quadratic form using substitution.

The general form of quadratic equation is given by:

ax^{2}+bx+c=0

So let us say

(x-5)^{2}=u.......(2)

Plugging the value of (x-5)² from equation (2) in (1),

6u^{2}+4u+6=0

Answer : Option B. 6u^{2}+4u+6=0
