1. The cosine function is one-to-one on the interval (0,r) arccos(x) = 0 with domain [-1.1] so we can define the inverse of cosine function cos¹(x) = 2. The independent variable, x, in the function sin¹(a) represents the values of sine function and these values lie in the interval [-1, 1]. true 3. The values of the tan¹ (2) are in the interval [-]. it is true 4. The range of the function tan¹(x) = arctan(x) = 0 is (-). false statement 5. The function sin() is one-to-one in the interval (-). it is not true V V
