integral of e^{x+y}

\int e^{x + y} d y

e^{x + y} + C

Solution steps

\int e^{x + y} d y

e^{x + y} = e^{x} e^{y}

= \int e^{x} e^{y} d y

Take the constant out:

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

= e^{x} \cdot \int e^{y} d y

Use the common integral:

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

= e^{x} e^{y}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

e^{x} e^{y} = e^{x + y}

= e^{x + y}

Add a constant to the solution

= e^{x + y} + C

\frac{\partial}{\partial s} (\frac{s ^{2} + 4}{t - 3})

x \to 0 - lim (\frac{2 x}{∣ x ∣})

t y^{^{''}} - y^{^{'}} = t^{2} + t, y (1) = 1, y^{^{'}} (1) = 5
