cos(30)+sin(45)

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

\frac{3 + 2}{2}

Solution steps

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

Use the following trivial identity:

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

Use the following trivial identity:

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

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

Simplify

\frac{3}{2} + \frac{2}{2} : \frac{3 + 2}{2}

= \frac{3 + 2}{2}

2 tan (π)

sin ((\frac{π}{3})^{2})

csc (33.6 9^{\circ})

\frac{cos ( 0.1 ) - 1}{0.1}

cos (1) + sin (1)
