To use trigonometric functions, we first must understand how to measure the angles. Therefore f ( x) = sin ( x + π 6 ) − 2 can be rewritten as f ( x) = sin ( x − ( − π 6 ) ) − 2. step-by-step \int xsinx. The period of a function \(f\) is defined to be the smallest positive value p such that \(f(x+p)=f(x)\) for all values \(x\) in the domain of \(f\). By using a right-angled triangle as a reference, the trigonometric functions and identities are derived: sin θ = Opposite Side/Hypotenuse.
