cos(45)+sin(60)

cos (4 5^{\circ}) + sin (6 0^{\circ})

\frac{2 + 3}{2}

Solution steps

cos (4 5^{\circ}) + sin (6 0^{\circ})

Use the following trivial identity:

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

Use the following trivial identity:

sin (6 0^{\circ}) = \frac{3}{2}

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

Simplify

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

= \frac{2 + 3}{2}

sin (0) + 0 cos (0)

tan (1.6)

sin (\frac{- 7 π}{3})

arctan (\frac{6}{0})

sin (0.5)
