integral of 7xsec^2(x)

\int 7 x sec^{2} (x) d x

7 (x tan (x) + ln ∣ cos (x) ∣) + C

Solution steps

\int 7 x sec^{2} (x) d x

Take the constant out:

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

= 7 \cdot \int x sec^{2} (x) d x

Apply Integration By Parts

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

= 7 (x tan (x) - \int tan (x) d x)

\int tan (x) d x = - ln ∣ cos (x) ∣

= 7 (x tan (x) - (- ln ∣ cos (x) ∣))

Simplify

= 7 (x tan (x) + ln ∣ cos (x) ∣)

Add a constant to the solution

= 7 (x tan (x) + ln ∣ cos (x) ∣) + C

10000 - 9000 e^{- 0.3 t}

\frac{s}{( s - 1 ) ^{2}}

y = 2 x^{\frac{3}{2}}

\frac{\partial}{\partial x} (x^{2} y^{3} - 4 y)

\frac{d y}{d x}, 4 x y = 8
