Question

4. 4csc^2x+3cscx-1=0

Answer 1

Answer: 8cxs^c= -3 csc (x) +1

Step-by-step explanation:

To solve for c you need to simplify both sides of the equation, then isolating the variable

Answer 2

Answer:

x = - π/2   or x = - π/2 + 2nπ       n = integer

Step-by-step explanation:

4csc²x+3cscx-1=0

(csc x + 1) (4csc x - 1) = 0

csc x = - 1 or csc x = 1/4

1/ sin x = - 1      or 1 / sin x = 1/4

sin x = - 1      or sin x = 4  (x no solution when sin x = 4)

sin x = - 1

x = - π/2   or x = - π/2 + 2nπ       n = integer
