integral of (xsin(x))/((cos(x))^2)

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

x sec (x) - ln ∣ tan (x) + sec (x) ∣ + C

Solution steps

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

Rewrite using trig identities

= \int x sec (x) tan (x) d x

Apply Integration By Parts

: x sec (x) - \int sec (x) d x

= x sec (x) - \int sec (x) d x

\int sec (x) d x = ln ∣ tan (x) + sec (x) ∣

= x sec (x) - ln ∣ tan (x) + sec (x) ∣

Add a constant to the solution

= x sec (x) - ln ∣ tan (x) + sec (x) ∣ + C

\frac{5}{4 ( s - 3 ) ^{2} - 64}

\frac{d}{d x} (ln (\frac{x + 2}{x ^{2}}))

\frac{d}{d x} (x^{2} y^{4})

x \to 2 lim (x^{2} - 5)

\int 3 x^{2} + cos (x) d x
