(sin²x/sinx)+(sinx/cosx)
———————————–
(cosx/cosx)+(cos²x/cosx)
(sin²x cosx + sin²x)/(sinx cosx)
——————————————-
(cos²x + cosx) / cosx
=(sin²x cosx + sin²x)/(sinx cosx) × {cosx/(cos²x + cosx)}
={(sin²x cosx + sin²x)/sinx} × {1/(cos²x+cosx}
={sin²x(cosx + 1)/sinx} × {1/cosx(cosx + 1)}
= {sin²x / sinx} × {1/cosx}
= {sinx / 1} × {1/cosx}
= sinx / cosx
= tanx
