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

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

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
