sin(pi/3+pi/4)

sin (\frac{π}{3} + \frac{π}{4})

\frac{2 ( 3 + 1 )}{4}

Solution steps

sin (\frac{π}{3} + \frac{π}{4})

Rewrite using trig identities:

sin (\frac{π}{3}) cos (\frac{π}{4}) + cos (\frac{π}{3}) sin (\frac{π}{4})

= sin (\frac{π}{3}) cos (\frac{π}{4}) + cos (\frac{π}{3}) sin (\frac{π}{4})

Use the following trivial identity:

sin (\frac{π}{3}) = \frac{3}{2}

Use the following trivial identity:

cos (\frac{π}{4}) = \frac{2}{2}

Use the following trivial identity:

cos (\frac{π}{3}) = \frac{1}{2}

Use the following trivial identity:

sin (\frac{π}{4}) = \frac{2}{2}

= \frac{3}{2} \cdot \frac{2}{2} + \frac{1}{2} \cdot \frac{2}{2}

Simplify

\frac{3}{2} \cdot \frac{2}{2} + \frac{1}{2} \cdot \frac{2}{2} : \frac{2 ( 3 + 1 )}{4}

= \frac{2 ( 3 + 1 )}{4}

cot (- \frac{8 π}{3})

tan (\frac{1}{3})

cot (\frac{13 π}{6})
