Solution by Steps
step 2
Next, we look at b=(e1)e. This is a constant value and the asksia-ll calculator approximated it as 0.0659880358453125370767901875968464249385770482527964364024735415..., which is less than 1
step 3
Lastly, c=tan(1), which is also a constant value. The asksia-ll calculator provided the approximation 1.5574077246549022305069748074583601730872507723815200383839466056..., which is greater than 1
step 4
Since c is greater than 1, b is a positive number less than 1, and a is also less than 1 but variable, we can determine that c is the largest. Without knowing the exact value of z, we cannot compare a and b definitively. However, if z is positive, a will be less than b
D
Key Concept
Comparing constant and variable expressions
Explanation
To compare the given expressions, we evaluate the constant values and consider the variable expression's behavior for positive values of z. Since c is greater than 1 and b is a positive fraction, c is the largest. a is dependent on z, but for positive z, it will be less than 1 and potentially less than b.
