If tan square A = 2tan square B +1then find the value of cos 2A + sin square B....pls I want the answer currently.
tan2A=2tan2B+1sec2A-1=2(sec2B-1)+1sec2A=2sec2B-2+1+1sec2A=2sec2Bcos2A=2cos2BAlso,sin2A=1-cos2A=1-2cos2BAnd,cos2B=1/2.cos2AThen,sin2B=1-cos2B=1-1/2.cos2ANow,cos2A+sin2B=cos2A-sin2A+sin2B=2cos2B-(1-2cos2B)+1-cos2B=2cos2B-1+2cos2B+1-cos2B=3cos2B=2cos2B+cos2B=cos2A+cos2B
