Question

Enter 1.034 in the calculator and press the keys for inverse sine. Explain why the response will indicate that something is wrong.

Answer 1

sin value cannot be more than 1, so we get error when we try to find out inverse of sin for values greater than 1

Answer 2

remember the unit circle. we know its equation is: x^2 + y^2 = 1^2 right? here, the 1^2 refers to the radius square, but 1^2 gives a 1 back. that means anywhere you go on the circle from the center, the distance will be 1. so for that circle, the max value of the sin and cos even, will be 1(think of the top poiint on the circle) and the min for both sin and cos is -1. hope this helps
