表达式2: left parenthesis, 3 plus StartRoot, 2 , EndRoot times cos left parenthesis, "p" , right parenthesis minus sin left parenthesis, "p" , right parenthesis "t" , 1 plus StartRoot, 2 , EndRoot times sin left parenthesis, "p" , right parenthesis plus cos left parenthesis, "p" , right parenthesis "t" , right parenthesis 有图表。3+2·cosp−sinpt,1+2·sinp+cospt
定义域t最小值： negative 6−6
less than or equal to "t" less than or equal to≤t≤
定义域t最大值： 55
