Answer:
The next step is to find the point on the circle which makes a tangent line that passes through the outside point.
Step-by-step explanation:
A tangent line to a circle is a line that touches the circle at exactly one point. You need two points to draw a line. You already have one point and the circle, then you need the other point, which lies on the circle. These two points have to lie on the same line. Notice that there are two possible tangent lines.
Cos (x+y)/cos x sin y
= cos x cos y - sin x sin y / cos x sin y
= cos x cos y/cos x sin y - sin x sin y / cos x sin y
