Question

Find sin (-660) and tan (1050)

Answer 1

Answer:

0.8660254038

-0.5773502692

Step-by-step explanation:

Answer 2

sin (-660)= √3/2and tan (1050) = -1/√3

answers here.

sin (-660)=

sin ( -(360+300)) = - sin 300

=-sin (360-60)

=sin60 = √3/2

Step-by-step explanation:

tan (1050) = tan ((360*2)+230)

tan 230= tan (270-40)

cot(40)= cot(180-60)

-cot(60)= -1/√3
