I can't get this question to work out at all. Here is what is provided. 2.4638[cos(0.4964)-cos]-(-0.4964)=0.0785 His final answer is, 2.4638cos+ = 2.5843 Can someone provide a step by step. Spent the last hour messing around with trying to get it to work out. Its annoying cause I figured out all the integration he did and I get stuck on this.
