Question

Am nevoie cat mai repede .Multumesc !

Answer 1

a) stim ca functia arcsin este definita pe [-1,1]

deci  -1≤ x patrat -1≤1

        0≤x patrat≤2

        0≤x≤rad 2

si x≥0

deci D=[0,rad2]

b) f(0)+f(1)= arcsin(o patrat-1)+ arccos(rad 0) + arcsin (1 la patrat -1) + arccos (rad1)= arcsin(-1)+arccos(0) + arcsin(0) + arccos(1)= -phi/2+ phi/2 +0+0=0
