Answer

$\cos^{- 1} (- 0.52) = 2.09 radians$

Steps

Step 1 ： $\sin^{- 1} (1.17)$ : Since 1.17 is not in the domain of $\sin^{- 1} (x)$ , this expression is undefined.

Step 2 ： $\tan^{- 1} (0.46)$ : This is within the domain of $\tan^{- 1} (x)$ , so we can calculate it. Using a calculator, we find that $\tan^{- 1} (0.46) \approx 0.43$ radians (rounded to the nearest hundredth).

Step 3 ： $\cos^{- 1} (- 0.52)$ : This is within the domain of $\cos^{- 1} (x)$ , so we can calculate it. Using a calculator, we find that $\cos^{- 1} (- 0.52) \approx 2.09$ radians (rounded to the nearest hundredth).

Step 4 ：So, the solutions are:

Step 5 ： $\sin^{- 1} (1.17) = Undefined$

Step 6 ： $\tan^{- 1} (0.46) = 0.43 radians$

Step 7 ： $\cos^{- 1} (- 0.52) = 2.09 radians$
