sec times tan times sin equals?

Is that:



?

Convert the sec and tan ratios into sin and cos ratios first.

if it is secθ x tanθ x sinθ , then its pretty simple
secθ = 1/tanθ
1/tanθ x tanθ x sinθ
the 1/tanθ will cancel with the tanθ
so
secθ x tanθ x sinθ = sinθ since the first two terms cancel each other out

That is not correct.
