Find all points on the curve x=4cos(t),y=4sin(t) that have the slope of 12.

.

Step-by-step explanation:

We need to find all the points on the curve x=4cos(t),y=4sin(t) that have the slope of 1/2.

Now,

So, slope of the curve is .

           ...(1)

Using , we get

Now,

It equation (1), tan(t) is negative. So, sin and cos have different signs.

If , then .

If , then .

Therefore, the two points are .

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.
