Use Inverse Functions to Express Solutions to Trigonometric

Use Inverse Functions to Express Solutions to Trigonometric Equations For Exercises 57-62, solve the equations on the interval 0, 2pi). Give the exact solutions in radians and give approximations in degrees rounded to 1 decimal place. tan x = -3

Solution

58 tanx = -3

x = tan^-1(-3) = -1.24905

interval [0,2pi )

x= pi -1.24905 , 2pi -1.24905

x= 1.8925 , 5.034 radians
