Question 867600: Solve each equation for solutions over the interval [0 degrees, 360 degrees) . Give solutions to the nearest tenth as appropriate. Sec^2 theta tan theta=2tan theta Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! Solve each equation for solutions over the interval [0 degrees, 360 degrees) . Give solutions to the nearest tenth as appropriate. Sec^2 theta tan theta=2tan theta
*** sec^2(x)tan(x)=2tan(x)
cancel out tan(x)
sec^2(x)=2
1/cos^2(x)=2
cos^2(x)=1/2
cos(x)=±1/√2=±√2/2
x=45˚, 135˚, 225˚, 315˚
