Sinh(x) * sin(x) and sinh(x) * cos(x)

• Thread starter Thread starter flufypancakes
• Start date Start date Oct 22, 2008

Click For Summary The discussion revolves around the mathematical expressions sinh(x) * sin(x) and sinh(x) * cos(x). A participant initially seeks clarification on these products, noting a relationship involving cosine. They express difficulty in applying the derived formula effectively. Ultimately, the participant resolves their query independently but invites further discussion on the topic. The conversation highlights the complexities of manipulating hyperbolic and trigonometric functions. flufypancakes Messages 11 Reaction score 0 anyone knows what's sinh(x)*sin(x)? or sinh(x)*cos(x)? i get sinh(x)sin(x) = 1/2[cos(x[i-1]) + cos(x[i+1])], but that doesn't help me much. any suggestions?

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap? View full post »
