Find the value of the trigonometric function sin (t) if sec(t)=-4/3 and the terminal side of angle t lies in quadrant II.

Question

a. sin(t)=3/4

b. sin(t)=(√7)/4

c. sin(t)=5/4

d. sin(t)=(√5)/4

Answer 1

Answer is B

Sec(t)=-4/3

cos(t)=-3/4

The angle is in second quadrant

Here sin is positive

 

sin(t)=sqrt(7)/4
