What is the integral of x^2sec(x^3-1)tan(x^3-1) ?

The integral of x^2sec(x^3-1)tan(x^3-1) is 1/3 sec(x^3-1)+C

integral of x^2sec(x^3-1)tan(x^3-1)

\int x^{2} sec (x^{3} - 1) tan (x^{3} - 1) d x

\frac{1}{3} sec (x^{3} - 1) + C

Solution steps

\int x^{2} sec (x^{3} - 1) tan (x^{3} - 1) d x

Apply u-substitution

= \int \frac{sec ( u ) tan ( u )}{3} d u

Take the constant out:

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

= \frac{1}{3} \cdot \int sec (u) tan (u) d u

Apply u-substitution

= \frac{1}{3} \cdot \int 1 d v

Integral of a constant:

\int a d x = a x

= \frac{1}{3} \cdot 1 \cdot v

Substitute back

= \frac{1}{3} \cdot 1 \cdot sec (x^{3} - 1)

Simplify

= \frac{1}{3} sec (x^{3} - 1)

Add a constant to the solution

= \frac{1}{3} sec (x^{3} - 1) + C

\int \frac{sin ( 2 t )}{2} d t

\int 4 x 5 - x^{2} d x

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

\int sin (x) sin^{2} (x) d x

\int 1 - 3 x^{2} d x
