Sin x/1+cos x=sec x-1/tan x
Jawaban Terkonfirmasi
Sinx / 1 + cosx = secx – 1 / tanx
sinx / 1 + cosx = 1/cosx – 1 / sinx/cosx
sinx / 1 + cosx = 1 – cosx / cosx / sinx/cosx
sinx / 1 + cosx = 1 – cosx / sinx
sinx / 1 + cosx = (1 – cosx)(1 + cosx) / sinx (1 + cosx
sinx / 1 + cosx = 1 – cos²x / sinx (1 + cosx)
sinx / 1 + cosx = sin²x / sinx (1 + cosx)
sinx / 1 + cosx = sinx / 1 + cosx
