Homework Statement
Solve the following equations in R.
arctan(1)=arctan(1/2)+arctan(x)
arctan(1/2)=arctan(1/3)+arctan(x)
arctan(1/3)=arctan(1/5)+arctan(x)
conclude that: pi=8arctan(1/5)+4arctan(1/7)+8arctan(1/8)
The Attempt at a Solution
For the first three i just took the tan of both sides and i got x=1/3 for the first one and x=1/7 for the second one and for the third one i got x=1/8. For the last one should i find the arctan(1/5) and the others from the first equations and plug them in or is there something else?
