sin(30)+sin(45)

sin (3 0^{\circ}) + sin (4 5^{\circ})

\frac{1 + 2}{2}

Solution steps

sin (3 0^{\circ}) + sin (4 5^{\circ})

Use the following trivial identity:

sin (3 0^{\circ}) = \frac{1}{2}

Use the following trivial identity:

sin (4 5^{\circ}) = \frac{2}{2}

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

Simplify

\frac{1}{2} + \frac{2}{2} : \frac{1 + 2}{2}

= \frac{1 + 2}{2}

e^{\frac{π}{4}} cos (\frac{π}{4})

\frac{sin ( 4 )}{4}

arctan (tan (- \frac{3 π}{7}))

sin (10 0^{\circ}) cos (4 0^{\circ}) - cos (10 0^{\circ}) sin (4 0^{\circ})

cos (0^{2})
