Ok I just posted the wrong question, and people never answer questions after a few answers... so here is the REAL question, my apologies.
5^x + 3^2x = 92
You have to use logs to solve it, and the answer in the back of the book is aprox. 1.93

I was wondering if anyone would tell me how to calculate an event in a combination problem. For example, how would you calculate 4 choose 2?
Is it a simple calculator function, or is it something more complex?
If anyone can help, that would be awesome!!!
Thanks

I'll be using Maple to figure this out, but I can't quite figure out the process. I need to find the minimum and maximum areas of a triangle if two of its vertices are (2,-1,0) and (3,2,2) and its third vertex is on the curve r->=<1+cost,sint,0>, t between 0 and Pi. To find the area of the triangle, I know I use 1/2 the cross product of the 2 vectors formed by the known vertices, but how to minimize the area I get stuck. Can anyone give me a clue?
