do you mean sin²Ф + cos Ф = 0

then heres ur ans

sin²Ф + cos Ф = 0

∴ 2 ( sin Ф × cos Ф) + cosФ = 0

∴cos Ф × 2( sin Ф+ 1 ) = 0

∴[ with the interval Ф ∈ ( 0 , 2 \pi ) ]

   cos Ф = 0                     or                   2 ( sin Ф + 1 ) = 0

    ∴ Ф = \pi/ 2                                           ∴ sin Ф = -1 / 2

                                                                ∴ Ф = 7 \pi / 6

hope u understood

give it a brainly mark pls
