Practicing Success
If $g(x)=∫\frac{dx}{x^{\frac{1}{2}}+x^{\frac{1}{6}}}$, then $g(1) - g(0)$ is: |
$4-\frac{3π}{2}$ $5-6log_e2$ $5+6log_e2$ $-4+\frac{3π}{2}$ |
$5+6log_e2$ |
Taking LCM of denominator of $\frac{1}{2}$ and $\frac{1}{6}$ which is 6 So $x = t^6$ $⇒ dx = 6t^5$ $g(x)=\int\frac{6t^5}{t^3+t}dt⇒\int\frac{6t^5}{t(t^2+t)}dt$ $⇒t\frac{6t^4}{(t^2+t)}dt⇒6\int\frac{(t^3+1)-1}{t^2+1}dt⇒6\int t^2-t+1-\frac{1}{t^2+1}$ |
