secA + tanA = x/y

rewrite each as function of only sine and cosine

1/cosA + sinA / cosA = x/y

/cosA + sinA / cosA = x/y1 + sinA x

/cosA + sinA / cosA = x/y1 + sinA x----------- = ------

/cosA + sinA / cosA = x/y1 + sinA x----------- = ------ cosA y

/cosA + sinA / cosA = x/y1 + sinA x----------- = ------ cosA yso cosA = y
