trigtan takes as argument an expression
containing trigonometric functions.
trigtan simplifies this expression with the formula :
sin(x)2+cos(x)2=1, tan(x)=sin(x)/cos(x) and
tries to rewrite the expression only with tangents.
Input :
^
4+cos(x)^
2+1)Output :
^
2/(1+(tan(x))^
2))^
2+1/(1+(tan(x)^
2)+1Output, after simplification with normal :
^
4+3*tan(x)^
2+2)/(tan(x)^
4+2*tan(x))^
2+1)
