# Step-by-step solutions of indefinite integral?

GROUPS:
 Hi guys, do you know how could I solve an indefinite integral with step-by-step solution and specifying the variable of integration? For example: WolframAlpha["cos(tw+f)cos(t*w)", IncludePods -> {"Indefinite Integral"}, PodStates -> {"Step-by-step solution", "Show all steps"}] in this case Mathematica chooses as variable of integrazion w, but I would variable of integration is t. I tried to lunch: WolframAlpha["[cos(tw+f)cos(t*w),{t}]", IncludePods -> {"Indefinite Integral"}, PodStates -> {"Step-by-step solution", "Show all steps"}] but doesn't work.Thank you for your help.

 If in Mathematica I enter =Integrate[Cos[t*w+f]Cos[t*w],t] and after WolframAlpha returns the result I tap on the grey + to show more information and then click on the orange step-by-step- solution then it shows me the steps and seems to use the correct variable of integrationUnfortunately I don't know how to translate that into your Pods.
