O is the centre of a circle. P is a point on its circumference. the gradiant of OP is 2. what is the gradient of tangent P.
can i also please have an explanation
is the centre of a circle. is a point on its circumference.
The gradient of is 2.
What is the gradient of the tangent at
We are expected to know this theorem:
The tangent to a circle is perpendicular to the radius to the point of tangency.
If the gradient of the radius is 2, then the gradient of the tangent is __ ?
