1.) (cos6theta+cos 4theta) +(5cos4theta+5cos2theta)+(10cos2theta+10cos 0)÷ (cos5theta+5cos3theta+10cos theta ). 2.) 2cos(6theta+4theta/2) ×cos(6theta-4theta/2) + 5[cos (4theta+2theta/2)×cos (4theta-2theta/2)]+ 10[2cos (2theta+0/2)×cos(2theta+0/2)].÷ (cos5theta+5cos3theta +10costheta) 3.) (2cos 5theta×costheta)+(10cos3theta×costheta)+(20costheta×costheta).÷ (cos5theta+5cos3theta +10costheta). 4.)2costheta[cos5theta+5cos3 theta+10costheta].÷(cos5theta+5cos3theta +10costheta). 5.) 2costheta. proved.....
