Question 865398: Solve the equation on the given interval, expressing the solution for x in terms of inverse trigonometric functions. (Enter your answers as a comma-separated list.)
(tan x)2 + 2 tan x − 63 = 0 on (−π/2, π/2)
You can put this solution on YOUR website! Solve the equation on the given interval, expressing the solution for x in terms of inverse trigonometric functions. (Enter your answers as a comma-separated list.)
(tan x)^2 + 2 tan x − 63 = 0 on (−π/2, π/2)
-----
Factor:
(tan(x)+9)(tan(x)-7) = 0
-----
tan(x) = -9 or tan(x) = 7
----
arctan(-9) = -1.46 radians
arctan(7) = 1.43 radians
