Question details

Indicate counterexamples to these universally quantified statements or indicate that there exists no cou terexample. Here, the domain for all variables consists of all real numbers. (No justification is needed. If there are several countereramples in the list, make sure to indicate all of the (a) Yr(r#3) (ii) 0 (iv)-Vi (v) There is no counterexample, i.e. the statement is true. (b) Vz ((エ20) → (r > 0)) (i) Vi (ii) 0 (iv) π (v) There is no counterexample, i.e. the statement is true. (i) v2 (ii) 0 (iv) π/2 (v) There is no counterexample, i.e. the statement is true. (i) v厚 (ii) 0 iv)3 (v) There is no i.e. the statement is true. (e) Vz ((sin(z) + 2cos(z-r) → (r--1)) (i) v厚 (ii) 0 (iv)3 (v) There is no counterexample, i.e. the statement is true.
