I have a digram with two circle touching at r. One has the letter A which is the in centre, and the other one has the letter B in the centre.The circle with centre A has radius 5cm and the circle...

Basically, the question is tan(x) = Tan(x). Obviously besides 0, what would be the same under tan and Tan?

A rocket's path is graphed by the function f(x) = x^3 - 8x, where x refers to time after launch (s). At what point after its launch would you release its thrusters in order for its tangent...
