For ease of convenience I'll only answer two questions

a. tanΦ - cosΦ
Recall tanΦ = sinΦ+cosΦ
therefore sinΦ+cosΦ - cosΦ = sinΦ
tanΦ - cosΦ = sinΦ

b. tanΦ + cosΦ
Recall tanΦ = sinΦ+cosΦ
therefore sinΦ+cosΦ + cosΦ = sinΦ + 2cosΦ
tanΦ + cosΦ= sinΦ + 2cosΦ

To simplify trigonometric expressions, the calculator uses various formulas of trigonometry, here are some examples of formulas trigonometric used by the calculator:

cos(−x)=cos(x)
sin(−x)=−sin(x)
tan(−x)=−tan(x)
cos(x+π2)=−sin(x)
sin(x+π2)=cos(x)
tan(x+π2)=1tan(x)
cos(x+π)=−cos(x)
sin(x+π)=−sin(x)
tan(x+π)=tan(x)
