Need help with the two problems sooooooo bad

Question

Find all solutions of the equation in the interval [0, 2𝜋) algebraically. Use the table feature of a graphing utility to check your answers numerically.

7 sec x csc x = 14 csc x

Find all solutions of the equation in the interval [0, 2𝜋). (Write your answer in terms of 𝜋. Enter your answers from smallest to largest.)

Answer 1

cscx(7secx - 14) = 0; cscx ≠ 0; 7secx = 14; cosx = 1/2 x = π/3 or x = 5π/3

sinx = - √3/2; x = 4π/3 or x = 5π/3
