pendulum swing --basic trig problems 1. The problem statement, all variables and given/known data lets say you have a pendulum swinging. the length of string is 1m it swings to the right so that the angle is 45deg. i want to find difference in height from when it is at rest to its new position at 45deg. How do i do this, trigonomically speaking i mean? i mean, where is the right triangle??? 2. Relevant equations not exactly a homework prob, but related to everything in homework 3. The attempt at a solution 1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution i think i forgot sum basic trig, cause i cant figure out where the right angle triangle is to get my lengths from/????
