integral from 0 to 2 of 4*2^{-x}-1

\int_{0}^{2} 4 \cdot 2^{- x} - 1 d x

\frac{3}{ln ( 2 )} - 2

Solution steps

\int_{0}^{2} 4 \cdot 2^{- x} - 1 d x

Apply the Sum Rule:

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

= \int_{0}^{2} 4 \cdot 2^{- x} d x - \int_{0}^{2} 1 d x

\int_{0}^{2} 4 \cdot 2^{- x} d x = \frac{3}{ln ( 2 )}

\int_{0}^{2} 1 d x = 2

= \frac{3}{ln ( 2 )} - 2

\int_{1}^{2} x arcsec (x) d x

\int_{0}^{1} (- ln (x))^{2} d x

\int_{1}^{4} \frac{x}{x - 1} d x

\int_{0}^{2 - x} (2 - x - y) d y

\int_{0}^{1} (1 - 8 x^{3} + 16 x^{7}) d x
