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:

cos ^{2}(x+pi/6) when x = 0.2sin ^{-1}(0.3x+0.2) when x = 1.345x ^{5}+ 4.567x^{3}- 0.202x + 4.312 when x =0.587exp(-0.4x ^{2})tan^{2}(x+2.1) ln(x+2.5) when x = 0.132
