Find the amplitude and period of ft=-tan0.4t

Answer

{"amplitude": 1, "period": 7.85398}

Q: What is the general form of the tangent function? A: The general form of the tangent function is y = A tan(B(x - h)) + k.
Q: How do we identify the amplitude and period of a tangent function? A: The amplitude is |A| and the period is π/B.
Q: What is the amplitude of ft=-tan0.4t? A: The amplitude is |A| = |-1| = 1.
Q: What is the period of ft=-tan0.4t? A: The period is π/B = π/0.4 = 7.85398.
