Question

lf sin 3/2 cos=-1/2 then ​

Answer 1

Answer:

First recognise that sin ( theta) / cos( theta) = tan ( theta)

tan( theta)= sqft (3)= 60 degrees or 240 degrees

now to determine the correct angle draw a unit circle

Draw a line for x = cos ( theta) = -1/2 on the graph

Drow a line for y= sin ( theta) = - sqrt 3) /2
