sin(25)cos(35)+cos(25)sin(35)

sin (2 5^{\circ}) cos (3 5^{\circ}) + cos (2 5^{\circ}) sin (3 5^{\circ})

\frac{3}{2}

Solution steps

sin (2 5^{\circ}) cos (3 5^{\circ}) + cos (2 5^{\circ}) sin (3 5^{\circ})

Rewrite using trig identities:

sin (6 0^{\circ})

= sin (6 0^{\circ})

Use the following trivial identity:

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

= \frac{3}{2}

cosh (ln (4))

sec (- 18 0^{\circ})

arccos (\frac{2}{6})

arccos (0.88)

cos (1 0^{\circ}) cos (8 0^{\circ}) - sin (1 0^{\circ}) sin (8 0^{\circ})
