sin(-1020)

Solution

sin (- 102 0^{\circ})

Solution

\frac{3}{2}

+1

Solution steps

sin (- 102 0^{\circ})

Use the following property:

sin (- x) = - sin (x)

sin (- 102 0^{\circ}) = - sin (102 0^{\circ})

= - sin (102 0^{\circ})

sin (102 0^{\circ}) = sin (30 0^{\circ})

= - sin (30 0^{\circ})

Rewrite using trig identities:

sin (30 0^{\circ}) = - \frac{3}{2}

= - (- \frac{3}{2})

Simplify

= \frac{3}{2}
