Question

Which equation should be used to graph y = sec^(-1)(x) on a calculator?

a) y = 1/sec(x)
b) y = 1/cos^(-1)(x)
c) y = sec(1/x)
d) y = cos^(-1)(1/x)

Answer 1

To graph y = sec^(-1)(x) on a calculator, use the equation y = 1/cos^(-1)(x).

Step-by-step explanation:

In order to graph the function y = sec^(-1)(x) on a calculator, you would need to use the equation y = 1/cos^(-1)(x). This is because the inverse of the secant function is the cosine function. Therefore, to find the values of y, you need to find the values of x using the cosine function and then take the reciprocal.
