Cotangent Function cot x1 - mix a = 1, b = 1, c = 0 và d = 0. Take lưu ý of the period, phase shift & positions of the asymptotes (vertical lines) of the graph of f? Now change a , how does it affect the graph? Does it affect its range? If yes, how?2 - mix a = 1, c = 0, d = 0 and change b. Approximate the period from the graph và compare it khổng lồ ( dfrac2pi b ). How does b affect the graph of f(x)? How does it affect the asymptotes of the graph of f?3 - phối a = 1, b = 1, d = 0 & change c starting from zero increasing slowly to lớn positive large values. Take note of the shift, is it khổng lồ the left or to lớn the right? Compare its measure to ( - c / b ).4 - mix a = 1, b = 1, d = 0 và change c starting from zero deceasing slowly to negative smaller values. Take chú ý of the shift, is it a left or a right shift? Compare its measure to lớn ( - c / b ).5 - set a,b & c khổng lồ non zero values and change d. What is the direction of the shift of the graph?6 - Which parameters affect the positions of the vertical asymptotes? Explain analytically.7 - Which parameters affect the domain name of the cotangent function? Explain analytically.8 - Which parameters affect the range of the cotagent function? Explain analytically.
