Question

Write the value of sin (-750)° give me they steps also​

Answer 1

Step-by-step explanation:

first of all we check in which quadrant sin (-750) will lie

sin(-750)

-sin750 because sin(-∅) be always -sin∅

sin750 lie in 1 quadrant and in 1st quadrant all ratios are positive

-(×)+ gives - so,

-(sin750)

-sin(180×4+30) sin(180+∅)= sin∅

-sin30

-1/2
