tan(2(pi/4))

tan (2 (\frac{π}{4}))

Undefined

Solution steps

tan (2 (\frac{π}{4}))

= tan (2 \cdot \frac{π}{4})

Rewrite using trig identities:

Undefined

tan (2 \cdot \frac{π}{4})

Use the Double Angle identity:

tan (2 x) = \frac{2 tan ( x )}{1 - tan ^{2} ( x )}

= \frac{2 tan ( \frac{π}{4} )}{1 - tan ^{2} ( \frac{π}{4} )}

Simplify

\frac{2 tan ( \frac{π}{4} )}{1 - tan ^{2} ( \frac{π}{4} )} :

Undefined

\frac{2 tan ( \frac{π}{4} )}{1 - tan ^{2} ( \frac{π}{4} )}

1 - tan^{2} (\frac{π}{4}) = 0

= \frac{2 tan ( \frac{π}{4} )}{0}

\frac{x}{0}

is undefined

= Undefined

= Undefined

= Undefined
