integral from 1 to x^2 of sin^2(t)

\int_{1}^{x^{2}} sin^{2} (t) d t

\frac{1}{2} (x^{2} - 1 - \frac{1}{2} (sin (2 x^{2}) - sin (2)))

Solution steps

\int_{1}^{x^{2}} sin^{2} (t) d t

Rewrite using trig identities

= \int_{1}^{x^{2}} \frac{1 - cos ( 2 t )}{2} d t

Take the constant out:

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

= \frac{1}{2} \cdot \int_{1}^{x^{2}} 1 - cos (2 t) d t

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \frac{1}{2} (\int_{1}^{x^{2}} 1 d t - \int_{1}^{x^{2}} cos (2 t) d t)

\int_{1}^{x^{2}} 1 d t = x^{2} - 1

\int_{1}^{x^{2}} cos (2 t) d t = \frac{1}{2} (sin (2 x^{2}) - sin (2))

= \frac{1}{2} (x^{2} - 1 - \frac{1}{2} (sin (2 x^{2}) - sin (2)))

\frac{\partial}{\partial x} ((x + 3 y)^{3})

(a + \frac{b}{x ^{2}})^{3}

f (x) = e^{4 x} + 4 e^{4 x} x

x \to \infty lim (\frac{ln ^{3} ( x )}{100 3 x})

\int 12 x e^{- 3 x} d x
