    How do i work out something like cos^2(x+pi/6) when x = 0.2

    i would like to use the software derive or MATLAB how do i go about doing this.

    on wolfram alpha i can just type it in but how do use other softwares


    also i would like to know how to this by hand.

    i have similar questions if you could help me on them too:

    cos2(x+pi/6) when x = 0.2
    sin-1(0.3x+0.2) when x = 1.345
    x5 + 4.567x3 - 0.202x + 4.312 when x =0.587
    exp(-0.4x2)tan2(x+2.1) ln(x+2.5) when x = 0.132
