Cosine, ciecle, hyperbolic cosine, arc length,The length of the arc MN of the graph of the hyperbolic cosine can be found with a compass. Draw a circle with center M and radius r equal to the y coordinate of the point N. Let P be the intersection of the circle with the x axis. The distance OP gives the arc lengthComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Matemática
