function not evaluating question tia sal2 Greetings All I trying to evaluate this function to a numerical value but it doesn;t seem to work I replace the expression with t sin t and it works what am I doing wrong? In[240]:= f = Function[{t}, 0.680232 Cos 6.28319 [t]] Out[240]:= Function[{t}, 0.680232 Cos 6.28319[t]] In[241]:= Evaluate [f[2.5]] Out[241]:= 0.680232 Cos 6.28319[2.5] Why am I not getting a numerical value? tia sal2
