    Sin square theta=cos square theta (squaring on both sides) 1_ cos square theta= cos square theta (sin square theta =1_ cos square theta) 1= cos square theta +cos square theta 1=2cos square theta 1/2=cos square theta 1/underroot2=cos theta. 1/2=cos square theta 1/2=1_sin square theta. Sin square theta =1_1/2=1/2. Sin theta=1/underroot2. 2 tan theta+cos theta = 2sin theta /cos theta +cos theta =2*1/underroot2 /1/underroot2 +1/underroot2 =2*1+1/underroot2 =2+1/underroot2=2*underroot2 +1/underroot2
