please help in mathematica
hello everyone. i am very new on mathematica.I have 2 problem :( at first, i have to eavluate the numerical equivalent of tan(45/Pi+Pi/45) when i wrote on mathematica like this:
In[21]:=
Tan[45/Pi+Pi/45]
Out[21]=
\!\(Tan[45\/π + π\/45]\)
it gives me that one. can not i get a real number from this?It doesn't solve tangent.i tried Solve[..] or Evaluate[..] but both they didnt work. And secondly how can i find the are of the region enclosed by the curves : y+45(x+45)=0 and y-x^3/45+45=0 ? i really don't have any idea about this. thanks for your helps from now.. it is very urgent i hope someone could help me :(
