Trig simplifying hp50g

[attle123]

hello,

when i was playing around with the hp50g, i was having a hard time of simplifying trig equations with tan() and sin() inside a single equation. E.g: if i wished to simplify (sin(x)^2)/cos(x), the answer would be sin(x)*tan(x). however i simply could not get the calculator to give this answer. Anyone able to give me a hand?


Thanks
