0=2Sin(((1/5)(10(22/7))+C)+1

Question

solve the equation

Answer 1

I take 22/7 to be π..

2sin(...)=-1, so (...)=sin^-1(-½)=7π/6 or 11π/6. The general solution is these angles +2πn where n is an integer.

⅕(10π+C)=7π/6+2πn or 11π/6+2πn,

2π+C/5=7π/6+2πn or 11π/6+2πn,

C/5=7π/6+2πn or 11π/6+2πn,

C=35π/6+10πn or 55π/6+10πn.
