Evaluate csc 7pi/6
a. -0.5
b. -2
c. 0
d. 2

B

Step-by-step explanation:

Using the trigonometric identity

csc x =

is in the third quadrant where sin < 0

The related acute angle is

→

Thus

sin () = - sin() = -

Hence

csc( = = - 2 → B

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
