integral of 5/(sqrt(t+4))

\int \frac{5}{t + 4} d t

10 t + 4 + C

Solution steps

\int \frac{5}{t + 4} d t

Take the constant out:

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

= 5 \cdot \int \frac{1}{t + 4} d t

Apply u-substitution

: \int 2 d u

= 5 \cdot \int 2 d u

Integral of a constant:

\int a d x = a x

= 5 \cdot 2 u

Substitute back

u = t + 4

= 5 \cdot 2 t + 4

Simplify

= 10 t + 4

Add a constant to the solution

= 10 t + 4 + C

\int 5 t^{5} d t

\int \frac{( 3 x ^{5} - 6 x ^{4} + 5 x ^{3} )}{x ^{4}} d x

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

\int \frac{9}{x} - 8 e^{x} d x

\int csc^{2} (x) + 1 d x
