Answer:
The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is 2π. So, a coefficient of b=1 is equivalent to a period of 2π. To get the period of the sine curve for any coefficient b, just divide 2π by the coefficient b to get the new period of the curve.

-1/2(-4/5)
Multiply the numerators by each other and do the same for the denominators.
That is:
-1(-4)=4
And 2*5=10
Now we have 4/10
Divide the numerator and the denominator by 2 to get 2/5 which is the simplest form.
Hope this helped.
