Find the exact value of sin-1(-0.5).

Step-by-step explanation:

To find : The exact value of .

We know that .

The range of   is between

Let

Hence, the principal value of  

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
