2arctan(e^0)

Solution

2 arctan (e^{0})

Solution

\frac{π}{2}

+1

Decimal

90

Solution steps

2 arctan (e^{0})

Use the following trivial identity:

arctan (e^{0}) = \frac{π}{4}

arctan (e^{0})

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}

= 2 \cdot \frac{π}{4}

Simplify

2 \cdot \frac{π}{4} : \frac{π}{2}

2 \cdot \frac{π}{4}

Multiply fractions:

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

= \frac{π 2}{4}

Cancel the common factor:

2

= \frac{π}{2}

= \frac{π}{2}
