begin mathsize 16px style Given space that space sinx space open parentheses sinx plus cosx close parentheses equals straight n If space we space put space straight x equals 0 space rightwards double arrow straight n equals 0 For space straight x equals 45 degree space or space 90 degree space we space will space get space straight n equals 1 Hence comma space total space number space of space integral space values space of space straight n space are space 2 space. Since comma space 45 degree space and space 90 degree space have space same space value space of space straight n. end style
