7 arctan (1)

Solution

\frac{7 π}{4}

+1

Decimal Notation

315

Solution steps

7 arctan (1)

Use the following trivial identity:

arctan (1) = \frac{π}{4}

arctan (1)

x 0 \frac{3}{3} 13 arctan (x) 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} arctan (x) 0^{\circ} 3 0^{\circ} 4 5^{\circ} 6 0^{\circ}

= \frac{π}{4}

= 7 \cdot \frac{π}{4}

Simplify

7 \cdot \frac{π}{4} : \frac{7 π}{4}

7 \cdot \frac{π}{4}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{π 7}{4}

= \frac{7 π}{4}
