Помогите пожалуйста, на завтра надобно безотлагательно!

1) 2arcsin(1/2) = 2/6 = /3; 4arccos(1/2) = 4/3 = 4/3;

/3 lt; 4/3 2arcsin(1/2) lt; 4arccos(1/2).

2) 4arctg1 = 4/4 = ; 5arccos(-1) = 5;

lt; 5 4arctg1 lt; 5arccos(-1).

3) 1arcsin1 = /2; 5arctg1 = 5/4;

/2 gt; 5/4 1arcsin1 gt; 5arctg1.

4) 5arccos0 = 51 = 5; 2arctg0 = 20 = 0.

5 gt; 0 5arccos0 gt; 2arctg0.

1) 4arcsin(3/2) - 4arcsin(-3/2) = 4/3 + 4/3 = 8/3

2) 4arccos(2/2) - 4arccos(-2/2) = 4/4 - 4( - /4) = - 43/4 = - 3 = -2.

3) 5arctg3 - 5arctg(-3) = 5/3 + 5/3 = 10/3

4) 2arctg(3/3) - 2arctg(3/3) = 0
