integral of 4/t

\int \frac{4}{t} d t

4 ln ∣ t ∣ + C

Solution steps

\int \frac{4}{t} d t

Take the constant out:

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

= 4 \cdot \int \frac{1}{t} d t

Use the common integral:

\int \frac{1}{t} d t = ln (∣ t ∣)

= 4 ln ∣ t ∣

Add a constant to the solution

= 4 ln ∣ t ∣ + C

2 y^{^{''}} + 32 y = 0

y = x^{3} - 6 x^{2} + 7 x + 3

\int \frac{( e ^{x} - e ^{- x} )}{e ^{x} + e ^{- x}} d x

\frac{x d y}{d x} = 5 x e^{x} - y + 9 x^{2}

\int 5 x^{2} e^{6 x} d x
