integral of 2^{5t^2}t

\int 2^{5 t^{2}} t d t

\frac{2 ^{5 t^{2} - 1}}{5 ln ( 2 )} + C

Solution steps

\int 2^{5 t^{2}} t d t

Apply u-substitution

: \int \frac{2 ^{u - 1}}{5} d u

= \int \frac{2 ^{u - 1}}{5} d u

Take the constant out:

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

= \frac{1}{5} \cdot \int 2^{u - 1} d u

Simplify

2^{u - 1} : 2^{u} \cdot 2^{- 1}

= \frac{1}{5} \cdot \int 2^{u} \cdot 2^{- 1} d u

Take the constant out:

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

= \frac{1}{5} \cdot 2^{- 1} \cdot \int 2^{u} d u

Apply exponent rule:

a^{- 1} = \frac{1}{a}

= \frac{1}{5} \cdot \frac{1}{2} \cdot \int 2^{u} d u

\int a^{x} d x = \frac{a ^{x}}{ln a}

= \frac{1}{5} \cdot \frac{1}{2} \cdot \frac{2 ^{u}}{ln ( 2 )}

Substitute back

u = 5 t^{2}

= \frac{1}{5} \cdot \frac{1}{2} \cdot \frac{2 ^{5 t^{2}}}{ln ( 2 )}

Simplify

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

= \frac{2 ^{5 t^{2} - 1}}{5 ln ( 2 )}

Add a constant to the solution

= \frac{2 ^{5 t^{2} - 1}}{5 ln ( 2 )} + C

\int x (ln (x) + 1) d x

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

\int \frac{x}{x ^{2} + 2} 7^{l n (x^{2} + 2)} d x

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

\int \frac{sec ^{4} ( x )}{tan ^{4} ( x )} d x
