Q4. The root of the equation f(x)=0 is found by using secant method. Given one of the initial estimates is x0=3 and f(3)=5, and the angle the secant makes with the function f(x) is 570, the next estimate of the root, x1, is -3.2470 -0.24704 3.2470 6.2470 Q5. For finding the root of sin(x)=0, the following choice of initial guesses would not be appropriate. and and and and Q6. When drugs are given orally to a patient, the drug concentration c in the blood stream is given by a formula c = Kte-atwhere K is dependent on parameters such as the dose administered while a is dependent on the absorption and elimination rates of the drug. If K=2 and a=0.25, where t is in seconds and c is in mg/ml, the time at which the maximum concentration is reached is given by the solution of the equation,
