Answer:
I don't know how to do it...
If you look at the graph of sin(n), you can notice that it oscillates every kpi/2 when k is odd. This oscillation proves that sin(n) diverges.
Move the constant to the right
5k=7-6
calculate
5k=1
solution: k=1/5 or k=0.2
Decimal Form: 0.45
Fraction Form: 45/100 or 9/20
I believe it should be 5.3487 since 283% is converted into 2.83 and multiplied by 1.89.
