Use the ALEKS calculator to evaluate each expression.Give your answers in radians.Round them to the nearest hundredth. If applicable, click on "Undefined."=cos−1−1.78 =sin−10.53 =tan−1−0.52

The expressions you provided involve inverse trigonometric functions. However, there seems to be a misunderstanding. The range of the cosine function is between -1 and 1. Therefore, cos^−1(-1.78) is undefined because -1.78 is outside this range.

For the other two expressions:

1. sin^−1(0.53): To find this, you would input 0.53 into the inverse sine function on your calculator. Make sure your calculator is in radian mode. The result is approximately 0.56 radians.

2. tan^−1(-0.52): To find this, you would input -0.52 into the inverse tangent function on your calculator. Again, ensure your calculator is in radian mode. The result is approximately -0.48 radians.

Remember to always check that your calculator is in the correct mode (degrees or radians) before performing these calculations.
