you draw a triangle formed by the centers of the two circles and use pythagoean theorem
it intersects the segment joining the centers of two circles
You times it by 2....UR WELCOME
196-164/2= 16
-pi/2 and pi/2
mostly it comes from memorization. If sin 30 = 1/2, then arcsin (1/2) = 30
it intersects the segment joining the centers of two circles
[1+(y')2]3 = [yy"+1+(y')2]2
Hey, this one is nice! I will venture the following: * 3: make them tangent in one point, with no intersection * 2: make them have a small intersection, ie. crossing in two points * 1: make them tangent from the inside * 0: make one fall completely within the other Giving the explanation would just be killing the imagination.

The question is suppose to read: Find the equation of the line tangent to y=(x²+3x)²(2x-2)³, when x=8
You times it by 2....UR WELCOME

236-124/2=56 degrees
I think you are referring to an Obround, which is a shape consisting of two semicircles connected by parallel lines tangent to their endpoints (or a rectangle with half a circle on each end)
The arc tangent is the recicple of the tangent which is also known as the cotangent. The tangent of π/2 is undefined, thus the cotangent would be zero.
They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.
the length of thr direct common tangent will be 2*{1/2 power of (r1*r2)} the answer will be 8 units in this case...
