what if question is silent about radians and degrees .... what to use.. ??

Both will be correct, if not mentioned .. but everything involving Calculus and Circular Measure is done in radians .. unless specified in the question (which they never will for those 2 to use degrees instead!)

Plz, need help here!
Q. Show that the line x+y=q will intersect the curve x^2-2x+2y^2=3 in two distinct points if q^2<2q+5.
In this, do we have to assume a value for q first? E.g. 2 would fit here. Is that fine or no?
