integral of 5/(cos^2(x))

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

5 tan (x) + C

Solution steps

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

Take the constant out:

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

= 5 \cdot \int \frac{1}{cos ^{2} ( x )} d x

Use the common integral:

\int \frac{1}{cos ^{2} ( x )} d x = tan (x)

= 5 tan (x)

Add a constant to the solution

= 5 tan (x) + C

\frac{d ^{2} y}{d x ^{2}} + 14 \frac{d y}{d x} + 98 y = 0

(3 x y^{2} + 1 y) d x + (3 x^{2} y + 1 x) d y = 0

\int cos (3 x) sin^{4} (3 x) d x

\frac{d y}{d x} = (4 x - 1) (y + 5)

\int (x + 2) (x - 2) d x
