Q. What is the period of the function\newlineh(x)=5sin(4x2)3 ?  h(x)=5 \sin (4 x-2)-3 \text { ? } \newlineGive an exact value.\newlineunits
  1. Determining the Period: The period of a sine function is determined by the coefficient of x inside the sine function. The general form of a sine function is \sin(bx), where the period is given by \frac{22\pi}{b}.\newlineIn the given function h(x) = 55\sin(44x - 22) - 33, the coefficient of x inside the sine function is 44.
  2. Using the Formula: To find the period of h(x), we use the formula for the period of a sine function, which is 2π2\pi divided by the coefficient of xx.\newlineThe period PP is therefore P=2π4P = \frac{2\pi}{4}.
  3. Calculating the Period: Perform the division to find the exact value of the period. P=2π4=π2P = \frac{2\pi}{4} = \frac{\pi}{2}.
  4. Checking for Errors: Check the calculation for any mathematical errors. The division is straightforward, and there are no complex operations, so the likelihood of a math error is low.
