WebMay 1, 2016 · The diagram shows part of the graph of a function whose equation is y = a sin ( b x ∘) + c. (a) Write down the values of a, b and c. (b) Determine the exact value of P where the graph intersects the x-axis as … WebThe period of the sine function is 2π. This means that the value of the function is the same every 2π units. Similar to other trigonometric functions, the sine function is a periodic function, which means that it repeats at regular intervals. The interval of the sine function is 2π. For example, we have sin(π) = 0.
