sin(45)-cos(60)

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

\frac{2 - 1}{2}

Solution steps

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

Use the following trivial identity:

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

Use the following trivial identity:

cos (6 0^{\circ}) = \frac{1}{2}

= \frac{2}{2} - \frac{1}{2}

Simplify

\frac{2}{2} - \frac{1}{2} : \frac{2 - 1}{2}

= \frac{2 - 1}{2}

- 40 sin (1) - 1

e^{6} \cdot 3^{2} - cos (3) ln (3) - 4

\frac{120}{tan ( 3 5 ^{\circ} )}

790 (9.81 \cdot cos (14. 3^{\circ}) - \frac{51.38 9 ^{2}}{298})

arcsin (\frac{14}{15})
