Use a calculator to find the value of the following expression rounded to two decimal places. \[ \tan ^{-1}(-0.7) \] $\tan ^{-1}(-0.7)=\square$ radian(s) (Type your answer in radians. Round to the nearest hundredth as needed.)

Step 1 ：The question is asking for the inverse tangent of -0.7, rounded to two decimal places. The inverse tangent function, also known as the arctangent function, is the inverse of the tangent function. It returns the angle whose tangent is a given number.

Step 2 ：Calculate the inverse tangent of -0.7.

Step 3 ：Round the result to two decimal places.

Step 4 ：Final Answer: \(\boxed{-0.61}\) radian(s)
