Solution steps

- 4 + 3 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}

= - 4 + 3 \cdot \frac{π}{4}

Simplify

- 4 + 3 \cdot \frac{π}{4} : - 4 + \frac{3 π}{4}

- 4 + 3 \cdot \frac{π}{4}
