Question Airspeed

Once again I have myself quite confused over the definitions of IAS, CAS, EAS & TAS. So if anyone could give me a hand to answer these two questions, it would take me from "im fairly sure im right" to "at least he thinks the same" ;o) , Cheers ;

Q1) When an aircraft climbs from sea level to altitude at a constant mach number, the true air speed (TAS) :-

a) Will decrease
b) Will increase
c) Remains constant

Q2) Given that an aircraft is in a climb but maintaining a particular indicated airspeed, the true air speed will:-

a) Increase
b) Decrease
c) Remain the same


Thankyou
