Here are a few Trig problems that I am having trouble with. Any help is greatly appreciated...
1. How many times more intense is a 7.1 richter earthquake than a 6.2 richter quake.
R = log (I/O)
2. Evaluate the value of each indicated trig function (SHOW ALL WORK). I can do this one, but I always forget to show all of my work...
If cos(B) = 4/5, and 3pi/2 < B < 2pi... Find Cot(-B), Cos(2B), and sin(2B)
3. Answer the question by decoding the message, Show all work...
What was trig?
