integral of t/(sqrt(3t^2-5))

\int \frac{t}{3 t ^{2} - 5} d t

\frac{1}{3} 3 t^{2} - 5 + C

Solution steps

\int \frac{t}{3 t ^{2} - 5} d t

Apply u-substitution

= \int \frac{1}{6 u} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{6} \cdot \int \frac{1}{u} d u

Apply the Power Rule

= \frac{1}{6} \cdot 2 u^{\frac{1}{2}}

Substitute back

u = 3 t^{2} - 5

= \frac{1}{6} \cdot 2 (3 t^{2} - 5)^{\frac{1}{2}}

Simplify

\frac{1}{6} \cdot 2 (3 t^{2} - 5)^{\frac{1}{2}} : \frac{1}{3} 3 t^{2} - 5

= \frac{1}{3} 3 t^{2} - 5

Add a constant to the solution

= \frac{1}{3} 3 t^{2} - 5 + C
