integral from 0 to y^2 of e^{-x}

\int_{0}^{y^{2}} e^{- x} d x

- e^{- y^{2}} + 1

Solution steps

\int_{0}^{y^{2}} e^{- x} d x

Apply u-substitution

= \int_{0}^{- y^{2}} - e^{u} d u

Take the constant out:

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

= - \int_{0}^{- y^{2}} e^{u} d u

Use the common integral:

\int e^{u} d u = e^{u}

= - [e^{u}]_{0}^{- y^{2}}

Compute the boundaries:

e^{- y^{2}} - 1

= - (e^{- y^{2}} - 1)

Simplify

= - e^{- y^{2}} + 1
