Pls help ASAP

solve the equation cosx - x mamerically using secant approach

For Exercises 63-68, use a graphing utility to solve the equation. Round the solutions to 4 decimal places. (See Example 12) 63. sinx = 1 – r 64. cos 2x = x - 2 65. cosx = In x 66. sinx = (In x)² 67. 3sinx = 0.5x + 1 68. 3cosx -0.5x + 1 %3D

Using Calculus, show that the two expressions are equivalent when n != 1

In Exercises 53-62, solve each equation on the interval [0, 27). 53. (tan x – 1)(cos x + 1) = 0 54. (tan x + 1)(sin x – 1) = 0 55. (2 cos x + V3)(2 sin x + 1) = 0 56. (2 cos x – V3)(2 sin x – 1) = 0 57. cot x(tan x – 1) = 0 58. cot x(tan x + 1) = 0 59. sin x + 2 sin x cos x = 0 60. cos x - 2 sin x cos x = 0 61. tan x cos x = tan x 62. cot? x sin x = cot? x

Solve sin(2x) + sin x = 0 for all solutions in the interval (0, 27). Enter exact radians. Hint The answers are

r=2(9+1)sin0
