arctan(1)-arctan(0)

arctan (1) - arctan (0)

\frac{π}{4}

Solution steps

arctan (1) - arctan (0)

Use the following trivial identity:

arctan (1) = \frac{π}{4}

Use the following trivial identity:

arctan (0) = 0

= \frac{π}{4} - 0

Simplify

= \frac{π}{4}

arctan (\frac{2}{7})

4 sin (\frac{2 π}{3})

csc (- 4 5^{\circ})

tan (- 2 π)

\frac{tan ( 2 0 ^{\circ} ) + tan ( 2 5 ^{\circ} )}{1 - tan ( 2 0 ^{\circ} ) tan ( 2 5 ^{\circ} )}
