integral of tan^2(x

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

\frac{x ^{2} tan ^{2} ( d )}{2} + C

Solution steps

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

Take the constant out:

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

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

Apply the Power Rule

: \frac{x ^{2}}{2}

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

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

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

Add a constant to the solution

= \frac{x ^{2} tan ^{2} ( d )}{2} + C

\frac{d}{d x} (ln (x))

x \to 2 - lim (- \frac{1}{x ^{2} - 4})

f (x) = 3 x - \frac{1}{x}

\frac{d}{d x} (0.04 e^{x} x^{2})

x \to 3 lim (j (x))
