Note: how to reduce this to c + atan(tan(d)*(2/x+1)) ?? |

\begin{reduce}
trigsimp(atan(((1+x)*sin(c+d)-sin(c-d))/((1+x)*cos(c+d)-cos(c-d))),tan);
\end{reduce}
Try Reduce calculations here. For example:
\begin{reduce} solve({z=x*a+2},{z,x}); int(sqrt(1-sin(x)*cos(x)),x); \end{reduce}
1: solve({z=x*a+2},{z,x}); | reduce |
int(sqrt(1-sin(x)*cos(x)),x); | reduce |
int(log(log(x)),x); | reduce |
integrate(log(log(x)),x)
(1) |
solve({y=-1/l*(1-(l*x+(-3*l^2-l+8)^(1/2)/4-0.5*l)^2)^(1/2) -(-3*l^2-l+8)^(1/2)/(4*l)+2*l}, {y}); | reduce |
