integral from 1 to 3 of 1

\int_{1}^{3} 1

2

Solution steps

\int_{1}^{3} 1 d x

Integral of a constant:

\int a d x = a x

= [1 \cdot x]_{1}^{3}

Simplify

= [x]_{1}^{3}

Compute the boundaries:

2

= 2

y^{^{''}} - y = t^{2}

\frac{z}{( 1 - z ^{2} )}

\int \frac{x ^{4} - 5 x ^{2} + 7}{x ^{4}} d x

\int (t - x)^{2} d x

\int - 5 x^{2} sec^{2} (3 x^{3}) tan^{5} (3 x^{3}) d x
