4secx^2tanx=8tanx

Apr 11th, 2015

Is this the correct question? You sure there is no plus or minus between 4sec^2x and tanx??? Let me know thanks

(4secx^2)(tanx)=8tanx

they are multiplied together 

i need the solutions in radians

ok, then 4secx^2=8, secx^2=2, secx=+/-sqrt of 2, x=sec^-1(sqrt of 2)=pi/4, x=sec^-1(-sqrt of 2)=3pi/4
