integral of-1/(t-2)

\int - \frac{1}{t - 2} d t

- ln ∣ t - 2 ∣ + C

Solution steps

\int - \frac{1}{t - 2} d t

Take the constant out:

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

= - \int \frac{1}{t - 2} d t

Apply u-substitution

: \int \frac{1}{u} d u

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

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= - ln ∣ u ∣

Substitute back

u = t - 2

= - ln ∣ t - 2 ∣

Add a constant to the solution

= - ln ∣ t - 2 ∣ + C

y^{^{'}} + 4 x y^{2} = 0

\frac{d y}{1 + 4 y ^{2}} = - \frac{x d x}{1 + x ^{4}}

\int \frac{5 x - 1}{( x + 1 ) ( x - 2 )} d x

x^{9}, at x = 1

\int \frac{4}{( x - 1 ) ( x + 3 )} d x
