Q. What is the period ofy=7sin(−43πx−4π)+6?Give an exact value.units
Period Determination: The period of a sine function is determined by the coefficient of x inside the sine function. The general form is y=a⋅sin(bx+c)+d, where ∣b∣2π gives the period.
Identify Coefficient: Identify the coefficient of x, which is −43π. The negative sign does not affect the period, so we can ignore it for this calculation.
Calculate Period: Calculate the period using the formula ∣b∣2π, where b is the coefficient of x. So, the period P=∣43π∣2π.
Simplify Expression: Simplify the expression for the period: P = \frac{\(2\)\pi}{\frac{\(3\)\pi}{\(4\)}} = \(2\pi \times \left(\frac{4}{3\pi}\right) = \left(\frac{8}{3}\right)\pi/\pi\.
Find Final Period: Cancel out the π in the numerator and denominator to find the period: P=38.
